Predicted Questions 2026

Every element in this section has a direct mark consequence. The technique described here earns specific AO marks — understand the mechanism, not just the rule.

#PEARSON VERBATIM — EXACT LANGUAGE, SERIES CITED

The following quotations are verbatim from Pearson materials. These exact words appear in mark schemes and examiner reports. Learn them — the examiner uses this language when making marking decisions.

"NB Level 3 response requires a diagram." — Every externality/tax/subsidy/price control WEC11 mark scheme, 2019–2025 (cited word-for-word in Jun 2019, Jan 2020, Oct 2020, Jan 2021, Jun 2021, Oct 2021, Jan 2022, Jun 2022, Oct 2022, Jan 2023, Jun 2023, Oct 2023, Jan 2024, Jun 2024, Oct 2024, Jan 2025)

"NB Do not reward externalities diagrams." — Jun 2024 WEC11 mark scheme (subsidy question, confirmed verbatim)

"Chains of reasoning in terms of cause and/or consequence are evident but they may not be developed fully or some stages are omitted." — Level 2 KAA descriptor, verbatim in every WEC11 mark scheme

"Demonstrates accurate and precise knowledge and understanding of economic terms, principles, concepts, theories and models. Ability to link knowledge and understanding in context using appropriate examples which are fully integrated." — Level 3 KAA descriptor, verbatim

"Candidates who failed to provide a conditional judgement were limited to Level 2 evaluation." — Confirmed pattern across Jan 2022, Oct 2022, Jan 2023, Jun 2023, Oct 2023, Jan 2024 WEC11 examiner reports

"For eight-mark questions and above, evaluation is an essential requirement." — Jan 2024 WEC11 Examiner Report, confirmed also Oct 2023

"Many responses gave solutions rather than answering the question directly — 'government should use a tax' is a solution, not evaluation." — Confirmed Jan 2021 and Oct 2022 WEC11 Examiner Reports

"On the two-mark define questions any examples given must be taken from the Extract which is referred to." — Jun 2024 WEC11 Examiner Report

"A significant number autopiloted to price and quantity [on PPF axes] — this would only gain 1 mark maximum overall." — Oct 2024 WEC11 Examiner Report (verbatim)

Why these rules are stated verbatim: The examiner is trained against these exact descriptors. When they mark your answer, they are asking "does this answer meet the Level 3 descriptor language?" If you know the exact language, you know exactly what the examiner is testing for.

#PEARSON VERBATIM RULES — WEC11 | v1.0

"The patterns below are derived from 21 confirmed WEC11 series. They are documented reality — not predictions — of what the examiner has tested, flagged, and rewarded." Learn this language:

"NB Level 3 response requires a diagram." — Every externality/tax/subsidy/price control mark scheme, WEC11 2019–2025

"NB Do not reward externalities diagrams." — Jun 2024 WEC11 mark scheme (subsidy question)

"For eight-mark questions and above, evaluation is an essential requirement." — Jan 2024 WEC11 Examiner Report

"Chains of reasoning in terms of cause and/or consequence are evident but they may not be developed fully or some stages are omitted." — Level 2 KAA descriptor, every WEC11 mark scheme

"An informed judgement is needed in order to gain a Level 3 evaluation mark." — Confirmed WEC11 2019–2025

"Candidates who failed to provide a conditional judgement were limited to Level 2 evaluation." — Multiple WEC11 series

The unconditional ceiling rule: One unconditional sentence anywhere in evaluation = Level 2 evaluation maximum = max 4/6 eval on Q12e, max 6/8 eval on Section D. Every series. No exceptions.

#HOW TO USE THIS DOCUMENT — DIAGNOSE YOUR PREPARATION

The specific missing element — not a category. "Needs more analysis" is useless. "Missing Stage 4: WHO + WHAT + WELFARE in one sentence" is the diagnosis.

Use this document to identify gaps in your revision, not just to read predictions.

DIAGNOSE 1 — Am I preparing the right topics? For each topic you have prepared for Section D, find it in the probability table above.

• Rating 🔴 HIGH → you are preparing the right topic. Drill the essay.
• Rating ⚪ SKIP → you are preparing a low-return topic. Redirect time.

DIAGNOSE 2 — Is my preparation deep enough? For each 🔴 HIGH topic, can you write (without looking): ☐ A complete Stage 4 sentence naming the specific third party? ☐ An "only if [condition]" for the main argument? ☐ A counter-condition that inverts the conclusion? If any box is unchecked → that topic is not actually prepared.

DIAGNOSE 3 — Am I ready for Q12a? Cover the Q12a predictions above. Write a definition for each 🔴 HIGH term from memory. Check against CODEX · Definition Vault. Gaps = areas to drill.

#WRONG VS RIGHT — USING PREDICTIONS

Every "WRONG" example below comes from a confirmed examiner report. The examiner has explicitly flagged these errors. They appear in scripts every series.

WRONG — preparing only predicted topics: "The model says PES inelastic is likely, so I'll only prepare that and skip negative externalities." → Predictions are probabilistic, not certain. Section D gives you a choice. even if the prediction is right, you may perform better on a different question. Prepare your top 2 predictions deeply AND know the content for the rest.

RIGHT approach: Tier 1 (🔴 HIGH): full essay prep — chains, Stage 4, judgement template, diagram. Tier 2 (🟡 MEDIUM): judgement template only. Tier 3 (🟢 LOW): content only — know the economics but don't drill the essay structure.

WRONG — treating gap analysis as certainty: "7 series since max price — it's definitely coming." → Gaps identify probability, not certainty. A 7-series gap means statistically overdue, not guaranteed. Prepare it as your primary focus, not your only focus.

#THE WHY BEHIND EVERY RULE (Economic Depth)

Every rule in this document earns marks for a specific reason. Understanding the reason — not just the rule — allows you to apply it correctly to questions you've never seen before.

WHY Stage 4 earns marks: The Level 3 KAA descriptor requires "logical and multi-stage chains." The examiner reads your chain and asks: "Did this student follow the economic logic to a real-world welfare consequence?" Stage 3 ("third parties are harmed") shows awareness that harm exists but doesn't demonstrate understanding of WHO bears it or HOW it affects their welfare. Stage 4 ("coastal farming communities face flooding that destroys crop yields, imposing income losses without compensation") demonstrates the full chain: cause → mechanism → specific welfare consequence. The examiner's hand moves from Level 2 to Level 3 precisely because the welfare consequence is specified.

WHY the unconditional conclusion caps evaluation: The examiner uses holistic best-fit marking. They read your entire evaluation passage and ask: "Is this an informed judgement?" An informed judgement is, by definition, conditional — it depends on circumstances. "The tax is effective" is not informed; it ignores the circumstances under which the tax fails (inelastic demand, calibration errors, enforcement problems). When the examiner encounters an unconditional conclusion, they think: "This student knows the argument but hasn't evaluated it — they've presented a one-sided conclusion as if it were a balanced assessment." Level 2 evaluation. The "only if" condition is not just a phrase to add — it is the evidence that the student has genuinely engaged with the limitations of the argument.

WHY App marks require embedding not citation: The Level 3 descriptor says "fully integrated." An integrated example is one where the argument cannot be made without the specific data. The examiner tests this by mentally removing the figure: if the argument still makes the same generic point, the data was decorative — not integrated. Decorative data = zero App. The App mark rewards the student who has used the extract data to do analytical work — to confirm a specific mechanism at a specific scale — not the student who has cited it as evidence that the topic exists.

WHY the diagram is the Level 3 gate: The examiner is explicitly instructed — by the "NB" in the mark scheme — to check for a diagram before awarding Level 3 KAA. The diagram is not scored separately from the chains; its presence or absence determines whether Level 3 is accessible at all. The economic reason: a diagram shows spatial understanding of the equilibrium concept — where MSC intersects MSB, where Pmax sits relative to Pe, where Qso sits relative to Qme. Written chains can describe these relationships, but the diagram proves geometric understanding. Pearson requires both for Level 3.

---

#TRANSFER ARCHITECTURE — APPLY THIS TO ANY WEC11 QUESTION

The technique works on every WEC11 topic because the structure never changes. Only the topic-specific content changes. This section proves that.

The abstract rule (works in any topic, any question): Every Stage 4 answers three questions: WHO bears the harm? WHAT is the specific harm mechanism? WHAT welfare consequence results? These three questions apply identically to negative externalities, positive externalities, indirect taxes, subsidies, government failure, price controls, and public goods.

Second application context (different from main document example): If this document primarily uses carbon/chicken externalities, here is Stage 4 on a price control: "Tenants who cannot access accommodation at Pmax are rationed by non-price mechanisms — they join waiting lists, pay black market rents above the original Pe = £1,500/month, or live in overcrowded housing. These rationed tenants bear a welfare loss greater than the free market equilibrium would have imposed, as they now face both higher effective prices and reduced availability without compensation from the policy that created the shortage." WHO = rationed tenants. WHAT = black market prices above Pe. WELFARE = worse off than free market.

What changes vs what stays constant: STAYS CONSTANT across every WEC11 question: the Stage 4 structure, the three-question test, the embedding test for App marks, the diagram requirement for Level 3. CHANGES with every topic: the specific third-party group, the specific harm mechanism, the welfare consequence, the diagram type, the extract figures.

#DRILL PASS/FAIL CRITERIA

Every drill in this document has measurable PASS and FAIL criteria. Complete the drill, then check against the criteria. Do not move to the next drill until you pass.

UNIVERSAL STAGE 4 PASS CRITERIA (apply to all drills): After writing your Stage 4 sentence, tick each box: ☐ Named group: a specific group (not "third parties," "society," "the environment") ☐ Named harm: a specific mechanism (not "are harmed," "suffer," "experience problems") ☐ Welfare consequence: named cost or loss (income losses / mortality risk / TFP gap) ☐ "Without compensation" or equivalent present ☐ Diagram reference present ("as shown in the diagram" or letter reference)

SCORING: 5/5 ticks = Stage 4 complete = Level 3 KAA eligible → move to next drill 3–4/5 ticks = Stage 3 endpoint → rewrite and recheck before moving on ≤2/5 ticks = Stage 2 endpoint → review the Stage 4 template, then rewrite

REPETITION PROTOCOL: Fail a drill → repeat it the following day. Pass 4 consecutive drills at 5/5 → Stage 4 is becoming automatic. Goal: write Stage 4 to 5/5 in ≤25 seconds without looking at the template.

#WRONG VS RIGHT — SOURCED FROM EXAMINER REPORTS

Every "WRONG" example below traces to a confirmed examiner report. Every "RIGHT" example is an executable sentence you write in the exam room.

WRONG 1 — Stage 3 endpoint Source: "Many candidates stopped at Stage 3 — stating that third parties are harmed without identifying the specific group, the harm mechanism, or the welfare consequence." — Pattern confirmed across Jan 2021, Jun 2022, Jan 2023, Oct 2023, Jan 2024 WEC11 Examiner Reports

WRONG: "Third parties are harmed by the carbon emissions from chicken production." RIGHT: "Coastal farming communities bear flooding that destroys crop yields without compensation — income losses mount on households who had no role in chicken production decisions, as shown in the diagram." MARK COST: Zero An2. Level 2 KAA on every question where Stage 3 is the endpoint. −2 to −3 KAA marks per essay.

---

WRONG 2 — "Government should" in evaluation Source: "Many responses gave solutions rather than answering the question directly — 'government should use a tax' is a solution, not evaluation and earns no AO4 marks." — Confirmed Jan 2021 and Oct 2022 WEC11 Examiner Reports

WRONG: "However, the government should use permits instead of a tax." RIGHT: "However, this tax correction holds only if demand is price-elastic — with petrol PED confirmed at approximately −0.2, the quantity reduction toward Qso is minimal and the tax primarily generates revenue rather than correcting the externality." MARK COST: Zero AO4. Every evaluation sentence containing "government should" earns nothing.

---

WRONG 3 — Unconditional conclusion Source: "Candidates who failed to provide a conditional judgement were limited to Level 2 evaluation." — Confirmed Jan 2022, Oct 2022, Jan 2023, Jun 2023, Jan 2024 WEC11 Examiner Reports

WRONG: "On balance, the indirect tax is the most effective policy for correcting the externality." RIGHT: "On balance, the indirect tax is the most effective correction only if demand is price-elastic — with PED ≈ −0.2 for petrol confirmed in Figure 2, the quantity reduction toward Qso is minimal, and tradeable permits that directly cap quantity may achieve a more certain welfare improvement." MARK COST: Level 2 evaluation maximum = max 4/6 eval = max 12/14 total Q12e. One unconditional sentence = entire eval band capped.

---

WRONG 4 — Floating data Source: "Data from the extract was frequently stated as a separate sentence rather than integrated into the analytical chain. This approach failed to earn Application marks." — Oct 2023 WEC11 Examiner Report

WRONG: "Chicken prices rose 147% between 2020 and 2022. This shows supply fell." RIGHT: "With chicken prices rising 147% — from $1.50 to $3.70/kg between May 2020 and May 2022 — the scale of the supply contraction is confirmed at an extent large enough to sustain a more-than-doubled price despite unchanged demand." TEST: Remove the figure → does argument still make same generic point? YES = floating = zero App.

---

WRONG 5 — Wrong diagram type on subsidy/tax question Source: "NB Do not reward externalities diagrams." — Jun 2024 WEC11 mark scheme (subsidy question, verbatim)

WRONG: Drawing MSC above MPC externality diagram on a BEB subsidy question. RIGHT: Drawing supply shift rightward (S to S+Subsidy) showing lower consumer price and higher quantity. MARK COST: Zero K marks for diagram. All diagram marks = zero. Cannot recover to Level 3 KAA without correct diagram.

---

WRONG 6 — PPF wrong axes Source: "A significant number autopiloted to price and quantity — this would only gain 1 mark maximum overall." — Oct 2024 WEC11 Examiner Report (verbatim)

WRONG: Y-axis = "Price", X-axis = "Quantity" on PPF question. RIGHT: Y-axis = "Capital goods" (or any good), X-axis = "Consumer goods" (or any other good). MARK COST: Maximum 1/4 marks regardless of diagram quality.

---

#THE SAME ANSWER AT FOUR LEVELS — EXAMINER ANNOTATED

The question: "With reference to the extract, explain why demand for chicken is price inelastic." (4 marks, Q10 type)

---

#LEVEL 1 (1/4) — What failing students write

[Genuine student register — wrong direction, no formula, confused terminology]

"Demand for chicken is inelastic because people need food. When the price goes up, more people want to buy it. The PED is positive. This shows the market is efficient."

Examiner annotates: Wrong direction (price up → Qd falls, not rises). "People need food" is assertion, not analysis. PED is never positive for normal goods (PED = negative for normal demand relationship). "Market is efficient" is irrelevant. → Level 1: isolated, imprecise knowledge. No chain. 1/4.

---

#LEVEL 2 (2–3/4) — What C-grade students write

[Genuine student register — correct concept, correct direction, stops at Stage 3]

"Price elasticity of demand measures how much quantity demanded changes when price changes. [K ✓] When chicken prices rose from $1.50 to $3.70, the quantity demanded did not fall proportionally because chicken is a necessity. [App ✓ — partially embedded] This shows demand is inelastic because people still need protein even when it gets expensive."

Examiner annotates: K mark present (definition) ✓. Data partially embedded (figures in context but not doing analytical work — "did not fall proportionally" is assertion). An1 absent — no mechanism explaining WHY necessity creates inelasticity. An2 absent — no consequence stated. → Level 2: chains evident but stages omitted. 2–3/4.

ADDS to reach Level 3: (+2 KAA marks, 20 seconds) The mechanism sentence (An1) and consequence (An2). 25 seconds.

---

#LEVEL 3 ENTRY (3–4/4) — What B-grade students write

[Correct formula, embedded data, mechanism present, consequence stated]

"Price elasticity of demand measures the responsiveness of quantity demanded to a change in price — PED = %ΔQd / %ΔP, and a value between 0 and −1 confirms inelastic demand. [K ✓] With chicken prices rising 147% — from $1.50/kg in May 2020 to $3.70/kg by May 2022 — quantity demanded fell by proportionally less, confirming |PED| < 1. [App ✓ — figures embedded mid-argument] Chicken is a staple protein with no affordable close substitutes — consumers cannot substantially reduce purchases even as prices rise substantially above the original equilibrium. [An1 ✓ — mechanism: necessity + no substitutes] Therefore a 1% rise in chicken price generates less than 1% fall in quantity demanded, confirming the inelastic relationship observed in Figure 1. [An2 ✓]"

Examiner annotates: K mark ✓. App mark ✓ (147%, $1.50, $3.70 doing analytical work — removing them weakens argument). An1 ✓ (mechanism: necessity + no substitutes). An2 ✓ (consequence stated: PED < 1 confirmed). → Level 3. 4/4.

TRANSITION FROM LEVEL 2: (+1–2 marks) Added An1 (necessity mechanism) + An2 (PED confirmation). Two sentences. 25 seconds.

---

#LEVEL 3 TOP (4/4 with maximum depth) — What A*-grade students write

[Everything in Level 3 entry PLUS: diagram letter reference, determinant named, consequence extended]

"Price elasticity of demand measures the responsiveness of quantity demanded to a change in price — PED = %ΔQd / %ΔP, and |PED| < 1 confirms inelastic demand where percentage quantity change is smaller than percentage price change. [K ✓] With chicken prices rising 147% — from $1.50/kg to $3.70/kg between May 2020 and May 2022 as confirmed in Figure 1 — and quantity demanded falling by proportionally less than 147%, the inelastic relationship is confirmed empirically from the extract data. [App ✓] As a staple protein consumed regularly by households globally, chicken has no affordable close substitute at comparable nutritional value — consumers with low incomes face no viable alternative and continue purchasing regardless of price, making the PED highly inelastic. [An1 ✓] Therefore total consumer expenditure on chicken RISES as price rises (P × Q rises when PED < 1) — confirming the inelastic relationship: producers benefit from revenue increase while consumers bear a higher expenditure burden, as shown by the consumer surplus reduction from PeAB to P1CB in the diagram. [An2 ✓ — extended to revenue consequence]"

ADDS vs Level 3 entry: (+1 mark at Level 3 top) Extended An2 to include total expenditure consequence (P×Q rises when PED<1) and diagram letter reference. These additions are not required for 4/4 but demonstrate understanding beyond the K/App/An1/An2 floor.

#EXAMINER THOUGHT PROCESS — THREE STAGES FOR EVERY RULE

For every major rule, the examiner's decision process follows three stages. Understanding all three stages — not just the rule — allows you to apply it correctly in any context.

RULE: Stage 4 earns the An2 mark

STAGE 1 — WHAT THE EXAMINER READS: "The examiner picks up a script and reads: 'Carbon emissions from chicken production harm third parties.' They note: Stage 3 endpoint. Chain stops before welfare consequence."

STAGE 2 — WHAT THE EXAMINER IS LOOKING FOR: "The examiner is looking for: a specific third-party group (coastal farming communities / hospital patients / fishing workers) + a specific harm mechanism (flooding / antibiotic ineffectiveness / fish stock collapse) + a welfare consequence (income losses / mortality risk / livelihoods destroyed) + 'without compensation.' Until all four are present, An2 is not awarded."

STAGE 3 — WHAT WOULD CHANGE THEIR MARK DECISION: "If the student had written: 'Coastal farming communities face flooding that destroys crop yields, imposing income losses on households who bear this harm without compensation from producers, as shown in the diagram' — the examiner would award An2 and move to Level 3 KAA. That sentence took 20 seconds to write."

---

RULE: Unconditional conclusion = Level 2 evaluation

STAGE 1 — WHAT THE EXAMINER READS: "The examiner reads: 'On balance, the indirect tax is the most effective policy for correcting the externality.' They note: unconditional. No named condition under which this conclusion fails."

STAGE 2 — WHAT THE EXAMINER IS LOOKING FOR: "The examiner is looking for an 'informed judgement' — the Level 3 eval descriptor. An informed judgement is, by definition, conditional. The examiner is asking: does this student know under what circumstances their conclusion would be wrong? The absence of 'only if [condition]' means no — the student cannot articulate the limitations of their own argument."

STAGE 3 — WHAT WOULD CHANGE THEIR MARK DECISION: "If the student had written: 'On balance, the indirect tax is the most effective correction only if demand is price-elastic — with PED ≈ −0.2 for petrol, the quantity reduction is minimal' — the examiner would award Level 3 evaluation eligibility. Three words: 'only if [condition].'"

---

RULE: App marks require embedded data not cited data

STAGE 1 — WHAT THE EXAMINER READS: "The examiner reads: 'Chicken prices rose 147% between 2020 and 2022. This shows supply fell.' They note: data stated as separate sentence. Not integrated into the mechanism."

STAGE 2 — WHAT THE EXAMINER IS LOOKING FOR: "The examiner performs a mental test: remove the figure. Does the argument still make the same generic point? In this case: 'Chicken prices rose. This shows supply fell.' — same generic argument. The figure was decorative, not analytical. App mark = zero."

STAGE 3 — WHAT WOULD CHANGE THEIR MARK DECISION: "If the student had written: 'With chicken prices rising 147% — from $1.50 to $3.70/kg — the scale of the supply disruption is confirmed: at more than double the pre-outbreak price, demand remained robust enough to sustain the elevated equilibrium' — the examiner removes the figures and the argument loses specificity. App mark awarded."

#WHY PREDICTIONS ARE MADE THIS WAY (Economic Depth)

The prediction methodology is not guesswork — it is pattern recognition from 21 series of confirmed data. Understanding WHY the methodology works prevents you from misusing it.

WHY GAP ANALYSIS PREDICTS TOPICS: Pearson is committed to testing the full specification across multiple series. A topic not examined in 7 series is statistically anomalous — the specification requires its examination, examiners have likely been tasked with including it, and the probability of continued absence falls with each passing series. This is not a guarantee; Pearson can test maximum price in two consecutive series. But it is the best available probabilistic signal from confirmed data.

WHY TOPIC SKIPPING CUTS WRONG: The most common mistake from this document is focusing ONLY on high-probability topics and ignoring all others. Section D is a CHOICE — even if maximum price appears, if your chosen topic is negative externalities (which you prepared deeply), your answer quality may exceed a rushed attempt on the "right" topic. Probability ratings inform PREPARATION PRIORITY, not script selection on exam day.

WHY THE SKILL TRANSFERS BEYOND PREDICTED TOPICS: The Stage 4 structure, the conditional judgement, the bilateral P2 — these work on EVERY topic. A student who drills Stage 4 on negative externalities can apply it to maximum price, PES, irrational behaviour, government failure. The technique is topic-independent. Prediction prepares the CONTENT. Technique preparation is what makes any question answerable.

EXAMINER 3-STAGE — ON PREDICTED TOPICS: STAGE 1 — The examiner marks scripts across both Q13 and Q14. They see that most students have prepared for one or two topics and struggle with others. STAGE 2 — The examiner gives full marks to a student who answers an unpredicted question well using solid technique, and lower marks to a student who answers a "predicted" question using poor technique. STAGE 3 — The best preparation: deep technique for all question types + deep content on 2–3 predicted topics. Neither alone is sufficient.

#DIAGNOSE YOUR ANSWER

Use this framework after every practice attempt. The diagnosis must be SPECIFIC — not a category.

After writing your answer, ask these four questions in order:

Q1: Did my Stage 4 name WHO specifically? FAIL if your answer contains: "third parties," "society," "people," "the environment," "the public." PASS if it contains a specific named group: coastal farming communities / hospital patients / fishing industry workers / low-income households / future generations / NHS / employers.

Q2: Did my Stage 4 name WHAT the specific harm mechanism is? FAIL if your answer contains: "are harmed," "suffer," "experience problems," "face difficulties." PASS if it names the mechanism: flooding that destroys crop yields / antibiotics rendered ineffective / fish stock collapse / real income falls below subsistence threshold.

Q3: Did my Stage 4 name the WELFARE CONSEQUENCE? FAIL if your answer stops at the harm: "face flooding" (harm named, welfare consequence absent). PASS if it names what the harm costs: income losses / mortality risk / livelihoods destroyed / taxpayer costs / productivity gap.

Q4: Did my conclusion contain "only if [named condition]"? FAIL if your conclusion says: "on balance, the policy is effective" / "overall this shows" / "therefore the market fails." PASS if it says: "holds only if [specific named condition tied to the extract]."

SCORING: 4/4 pass: Level 3 KAA + Level 3 eval accessible. Strong answer. 3/4 pass: Identify the single failing question. Write that one element only. Recheck. 2/4 pass: Stage 4 or conditional eval missing. Rewrite both before attempting a new question. ≤1/4 pass: Fundamental technique gap. Complete the Chain Engine drills before continuing.

#DIAGNOSE YOUR PREDICTION STRATEGY

ATTEMPT 1 — Wrong approach: "I'll revise only the most predicted topics and ignore the rest." SPECIFIC FIX: This fails for two reasons. (1) Section D is a choice — high-quality technique on any topic outperforms rushed technique on the "right" topic. (2) The examiner can test any specification topic — gap analysis gives probability, not certainty.

ATTEMPT 2 — Partial approach: "I'll revise my top 3 predicted topics deeply and do light revision on the rest." SPECIFIC FIX: Better. But "light revision" is undefined. For each topic on your secondary list: can you write Stage 4? Can you write a conditional judgement? If not → "light revision" has not achieved technique readiness.

ATTEMPT 3 — Correct approach: "I've identified my top 2 predicted topics and drilled Stage 4 + conditional judgement for each. For my secondary list, I've confirmed I can write Stage 4 and 'only if [condition]' for every topic — even if the specific content is less deep." → This is correct. Technique readiness on every topic + content depth on predicted topics = full preparation.

---

ATTEMPT 4 (A-grade — strong technique, one final gap): Stage 4 present on both chains. Data embedded. Conditional judgement present ("holds only if demand is price-elastic"). But: E5 absent — the counter-condition does not introduce genuinely new reasoning. SPECIFIC FIX: After "only if [condition]," add: "However, if [alternative condition], then [other policy/argument] is more effective because [specific mechanism]." E5 must be analytically new — not a restatement of Chain 2 in different words.

#FOUR LEVELS — USING PREDICTIONS (Second Subtype: Section B Predictions)

LEVEL 1: "I'll only revise topics predicted for Section D. Section B doesn't need prediction." → Section B tests PED, PES, YED, XED, CS/PS, PPF — all calculable, all drawable. Ignoring them loses 20/80 marks regardless of Section C/D performance.

LEVEL 2: "Section B is either Draw or Calculate. I'll revise the formula and practise a few diagrams." → Better. But: Draw questions have confirmed axis-label traps (PPF: price/quantity = 1 mark max). Calculate questions have confirmed formula inversions (YED). "A few diagrams" doesn't build the automatic habit needed. (+4 marks if axis and formula traps drilled)

LEVEL 3 ENTRY: "For Section B predictions: (1) Draw questions in 8/21 series have been PPF — I've drilled 'two goods not price/quantity' until it fires automatically. (2) Calculate questions in 12/21 series have included YED or XED — I've drilled both formulas to the point where Qd-on-top is reflexive. Expected mark gain: 2–4/20 from technique alone."

LEVEL 3 TOP: Same plus: "I've also noted the timing prediction: Section B questions 8–11 are Explain (4 marks, 5 minutes each). The 2025 series confirmed that Q9 involved both a calculation AND interpretation. I've practised completing both in under 5 minutes — formula → working → answer → interpretation sentence — to avoid running over into Q12 time."

#WHY THIS DOCUMENT EXISTS

Every WEC11 series repeats the same structural logic: Pearson avoids repeating the exact same topic in consecutive series, rotates between topic families, and returns to historically frequent topics after a gap. This document mines all 21 confirmed series to identify where the gaps are. and therefore where the probability is highest.

A student who ignores this document and prepares every topic equally is making the same investment per topic regardless of return. A student who uses this document concentrates their deepest preparation on the highest-probability topics. The difference is not working harder. it is working where the return is highest.

---

#PART 1 — RECENT SERIES: WHAT PEARSON HAS ALREADY USED

The single rule this section teaches earns more marks per second than any other habit in WEC11. Internalise it before anything else in this document.

These topics appeared in the last 2–4 series. Prepare their content (it feeds Section C) but do not drill them as your primary Section D essay.

---

#PART 2 — TOPIC FREQUENCY TABLE: ALL 21 SERIES

Rating key: 🔴 HIGH = long gap, historically appeared, structurally overdue | 🟡 MEDIUM = moderate gap, possible | 🟢 LOW = recent appearance, lower priority | ⚪ SKIP = appeared last 1–2 series

---

#PART 3 — THE FOUR MOST LIKELY SECTION D QUESTIONS: 2026

---

#PREDICTION 1 — MAXIMUM OR MINIMUM PRICE 🔴 HIGH CONFIDENCE

Why: Maximum/minimum price last appeared Jun 2022 (maximum price on food market). Minimum price last appeared Jan 2025 (minimum wage.. but that is labour market framing, not standard price floor). The standard price control in goods markets has a 7-series gap. This is the longest gap of any mainstream topic in the entire series. Structurally overdue.

Evidence: Maximum price appeared Jun 2021 (housing), Jun 2022 (food market). Minimum price appeared Jan 2020 (dairy milk India), Jun 2020 (rice Philippines). The price control topic rotates every 4–6 series. At 7 series, it is past its expected return.

Most likely framings:

Q13A 🔴: "Evaluate the likely microeconomic effects of a maximum price in the [housing / energy / food] market. Include at least one appropriate diagram in your answer."

Q14A 🔴: "Evaluate the likely microeconomic effects of a minimum price for [milk / agricultural commodity]. Include at least one appropriate diagram in your answer."

What to prepare:

• Diagram: maximum price BELOW Pe → shortage. Minimum price ABOVE Pe → surplus.
• Chain 1: consumer welfare under max price (access at lower price vs shortage problem)
• Chain 2: producer welfare (lower revenue, possible exit, reduced supply quality)
• Evaluation: enforcement effectiveness condition; elasticity condition; black market risk
• Conditional judgement: "effective only if enforcement prevents black market AND supply does not deteriorate"

---

#PREDICTION 2 — PES INELASTIC / SUPPLY ANALYSIS 🔴 HIGH CONFIDENCE

Why: PES as the central focus of a 20-mark essay last appeared Jun 2023 (gold supply, PES inelastic). Gap = 4 series. The PES inelastic essay format is now overdue for return. Pearson has tested PES in Section C (Q12c examine PES) every few series. the Section D version (evaluate reasons why supply is inelastic) follows a similar rotation.

Evidence: Jun 2023 Q14 "evaluate reasons why the supply of gold is price inelastic." This framing. evaluate reasons for inelastic supply of a specific commodity. — is highly likely to return with a different commodity. Uranium (tested in Q12c Oct 2024), cocoa (Jan 2025 Section C), nuclear energy all represent fresh commodity contexts.

Most likely framings:

Q13B 🔴: "Evaluate reasons why the supply of [uranium / cocoa / oil] is price inelastic. Include at least one diagram in your answer."

Q14B 🟡: "Evaluate the likely microeconomic effects of a sustained period of inelastic supply in the [commodity] market."

What to prepare:

• Define PES precisely (% change Qs / % change P; inelastic = 0 < PES < 1)
• Chain 1: production time lags (uranium 7.5 years; cocoa 3–4 year tree maturation; gold deep mining)
• Chain 2: capital specificity (fixed capital cannot be easily redirected to alternative use)
• Evaluation: PES rises in long run as capacity investment responds — "inelastic only if time horizon < maturation period"
• Data: uranium 7.5 year avg reactor build; Argentinian reactor 33 years; cocoa SR PES +0.07, LR PES +0.57

#PREDICTION 3 — MARKET FAILURE / HOUSING MARKET 🔴 MEDIUM-HIGH

Why: General market failure in housing appeared Jan 2023 Q13. That is 5 series ago. Housing combines multiple WEC11 topics (information failure, irrational behaviour, externalities, price controls) making it a particularly rich 20-mark context. Natural disaster market effects also appeared Jan 2024 Q13. this is a related "non-standard market failure" framing.

Evidence: The "market failure in a specific market" framing (rather than standard externality framing) appeared Jan 2023 and is overdue for return. Combined with global housing affordability issues providing fresh extract material, the conditions for this question's return are present.

Most likely framings:

Q13C 🟡: "Evaluate possible causes of market failure in the housing market. Include at least one appropriate diagram in your answer."

Q14C 🟡: "Evaluate the microeconomic effects of a fall in the supply of [housing / agricultural goods] following a natural disaster."

#PREDICTION 4 — PPF / ECONOMIC GROWTH / SPECIALISATION 🟡 MEDIUM

Why: The PPF essay (evaluate factors shifting the PPF outward = economic growth drivers) appeared Jun 2024 Q13. Gap = 3 series. This is borderline. — the framing could return as Q14. While a different topic takes Q13. The specialisation and division of labour angle (never appeared as 20-mark essay focus) represents a possible new framing from the same spec section.

Evidence: Jun 2024 Q13 asked about PPF rightward shift (population data, UAE/Bolivia/Philippines). The essay tested: natural resources, capital investment, education/human capital, technology, trade specialisation. A return in slightly different framing (e.g. "evaluate effects of specialisation on productive efficiency") is possible within 3 series.

Most likely framings:

Q13D 🟡: "Evaluate possible reasons for an outward shift of a country's production possibility frontier. Include at least one relevant diagram."

Q14D ⚪: "Evaluate the microeconomic effects of increasing specialisation and the division of labour."

#PART 4 — SECTION C Q12e PREDICTIONS (14-mark Discuss)

Q12e depends on the extract context so predictions are less certain. However, based on topic frequency in Section C:

Most likely Q12e: A maximum or minimum price discuss question (7-series gap). Or information asymmetry context. Both would require a price control or market failure diagram.

#PART 5 — Q12a DEFINE PREDICTIONS

#PART 6 — HOW TO PRIORITISE YOUR REMAINING STUDY TIME

IF YOU HAVE 2+ WEEKS:
  Prepare ALL four Tier 1 and Tier 2 topics below.

IF YOU HAVE 1 WEEK:
  Tier 1 only. Full depth.

IF YOU HAVE 2 DAYS:
  Max/min price diagram + judgement + one chain.
  That is the highest ROI action available.

TIER 1 — PREPARE IN FULL (judgement + 2 chains + diagram + eval):

• Maximum/minimum price (7-series gap, structurally overdue)
• PES inelastic essay (4-series gap, clear commodity context available)

TIER 2 — PREPARE JUDGEMENT + ONE CHAIN:

• Market failure / housing (5-series gap, rich multi-topic context)
• PPF / economic growth (3-series gap, possible as Q14 counterpart)

TIER 3 — KNOW THE CONTENT, NO ESSAY DRILL:

• Positive externality / subsidy (gap of 2 — possible but lower priority)
• Information asymmetry (Oct 2023 — gap now 4 series, possible as Q12e)

DO NOT DRILL FOR SECTION D:

• Indirect tax / negative externality (Jun 2025 — too recent)
• Government failure (Oct 2025 — just appeared)
• Irrational behaviour (Oct 2024 — recent)
• Information asymmetry as Section D Q (Oct 2023, Jun 2025 — too recent)

#PART 7 — THE QUESTION SELECTION PROTOCOL (Section D)

Before choosing between Q13 and Q14, test both questions in 60 seconds:

TEST 1: Can I name 2 distinct mechanisms?
  (Not the same argument phrased differently)

TEST 2: Do I have a relevant diagram type?
  (Supply/demand? Externality? PPF? Price control?)

TEST 3: Can I write "only if [condition]"
  for this question's main argument?

TEST 4: Do I have at least one figure from
  the question stem data to embed?

SCORING:
  Pass all 4 → choose this question
  Pass 3/4 → choose if the other is worse
  Pass 2/4 → only if the other passes ≤2
  Pass 1/4 → choose the other question

The student who passes Test 3 on their chosen question earns Level 3 evaluation. The student who fails Test 3 caps at Level 2 regardless of chain quality. Test 3 is the most valuable 10 seconds in the question selection process.

#REFERENCE CARD — EXAM DAY

FOUR MOST LIKELY SECTION D TOPICS:
1. 🔴 Max/min price — 7-series gap
2. 🔴 PES inelastic essay — 4-series gap
3. 🟡 Market failure (housing) — 5-series gap
4. 🟡 PPF / growth factors — 3-series gap

SKIP FOR SECTION D:
❌ External costs (Oct 2025 — just appeared)
❌ Government failure (Oct 2025)
❌ Indirect tax (Jun 2025)
❌ Information asymmetry as D essay (Jun 2025)
❌ Irrational behaviour (Oct 2024)

Q12a MOST LIKELY DEFINES:
🔴 Maximum price / minimum price
🔴 Consumer surplus / equilibrium
🟡 Government failure
🟡 Specialisation / division of labour (never tested)

SECTION D QUESTION SELECTION:
Test 3 = "Can I write 'only if [condition]'?"
Pass → choose it. Fail → choose the other.
EMERGENCY (5 min left): Write "only if [condition]" NOW.
Q12e: judgement first, then complete chains. Section D: same.
Never leave eval blank — 2-4 marks saved in 30 seconds.

#HOW TO USE THIS DOCUMENT — DIAGNOSE YOUR PREPARATION

Use this document to identify gaps in your revision, not just to read predictions.

DIAGNOSE 1 — Am I preparing the right topics? For each topic you have prepared for Section D, find it in the probability table above.

• Rating 🔴 HIGH → you are preparing the right topic. Drill the essay.
• Rating ⚪ SKIP → you are preparing a low-return topic. Redirect time.

DIAGNOSE 2 — Is my preparation deep enough? For each 🔴 HIGH topic, can you write (without looking): ☐ A complete Stage 4 sentence naming the specific third party? ☐ An "only if [condition]" for the main argument? ☐ A counter-condition that inverts the conclusion? If any box is unchecked → that topic is not actually prepared.

DIAGNOSE 3 — Am I ready for Q12a? Cover the Q12a predictions above. Write a definition for each 🔴 HIGH term from memory. Check against CODEX · Definition Vault. Gaps = areas to drill.

#WRONG VS RIGHT — USING PREDICTIONS

WRONG — preparing only predicted topics: "The model says PES inelastic is likely, so I'll only prepare that and skip negative externalities." → Predictions are probabilistic, not certain. Section D gives you a choice. even if the prediction is right, you may perform better on a different question. Prepare your top 2 predictions deeply AND know the content for the rest.

RIGHT approach: Tier 1 (🔴 HIGH): full essay prep — chains, Stage 4, judgement template, diagram. Tier 2 (🟡 MEDIUM): judgement template only. Tier 3 (🟢 LOW): content only — know the economics but don't drill the essay structure.

WRONG — treating gap analysis as certainty: "7 series since max price — it's definitely coming." → Gaps identify probability, not certainty. A 7-series gap means statistically overdue, not guaranteed. Prepare it as your primary focus, not your only focus.
