Paper 4 — The Global Economy

Forty Eight Hour Checklist

Provenance: compiled 2026-09-29. This document does no new primary-source extraction — it is a synthesis layer sitting on top of work already verified elsewhere in this course, and cites only material those documents already established: research/veridian/WEC14-verified-facts.md (the provenance-checked facts bank — 14 real exam series, October 2020–January 2025, 13 with a matching examiner report, plus a narrower later pass on one June 2025 question), content/veridian/technique-hub/wec14/forge-exam-technique-guide.md (§1–§6), content/veridian/technique-hub/wec14/codex-definitions-and-application-bank.md (Parts 1–2), and content/veridian/technique-hub/wec14/signal-frequency-and-boundaries.md (§1–§2). Where this document repeats a fact from one of those, it cites the section rather than re-deriving it. It adds two things none of the other three provide: a time-blocked 48-hour schedule, and a retrieval-practice self-test built as short-answer prompts rather than a re-mark-your-own-working checklist (that already exists, at FORGE §3).

#WEC14 — 48-Hour Pre-Exam Checklist

#Pearson Edexcel IAL Economics, Unit 4: Developments in the Global Economy

#0. What this is, and what it deliberately is not

This is a schedule and a self-test, not a fourth explanation of the paper. Three documents already sit in this folder and cover the material in depth: forge-exam-technique-guide.md (how each tariff on the paper actually converts an answer into a mark, plus its own self-mark checklist and exam-day protocol), codex-definitions-and-application-bank.md (every key term and a bank of real, grounded application paragraphs), and signal-frequency-and-boundaries.md (what actually recurs, by spec sub-section, across the series this course has fully read, plus real published grade-boundary data). This document does not re-teach any of that. It answers a narrower, time-bound question: given 48 hours left, in what order, and what do you deliberately leave alone.

Everything below traces to the same verified series those three documents already cite — 14 series read in full (October 2020–January 2025), 13 with a matching examiner report (June 2021's is missing from the archive), plus a narrower later check on isolated June 2025 questions. Nothing here invents a new trap, a new frequency figure, or a grade boundary. Where the underlying research is thin or absent for a sub-point, that is stated rather than filled in.

#1. The 48 hours, block by block

This assumes the exam is on the morning of T-0. Shift the clock, not the order, if yours is an afternoon sitting.

#T-48 to T-30 — the last full re-read (do this once, not twice)

Re-read forge-exam-technique-guide.md §2 in full — specifically the rule that the evaluation requirement's real cutoff on Section B sits between the 6-mark and 8-mark parts, not between Section B and Section C: write no evaluation on the 6-mark "analyse/examine two" part (it earns nothing there), and write it on the 8-mark part. This single distinction is confirmed independently across two series four years apart and is the highest-return re-read in this whole window, because it changes how you allocate a sentence, not what you know.
Re-read signal-frequency-and-boundaries.md §1's topic table once, to rank a re-read, not to predict a question. Balance of payments/exchange rates/competitiveness is confirmed in 10 of 14 series read — the deepest, most consistent coverage in the archive — and terms of trade is independently named the single weakest-answered Section A question in 5 of 13 examiner reports checked. Both are worth a re-read of their curriculum lesson's trap-taxonomy in this block; a sub-point sitting at 0–2 of 14 (public expenditure, patterns of trade, conflicts between blocs and the WTO) is under-sampled by this course's own research, not confirmed unimportant — see §4 below for what that means for your last 48 hours specifically.
Pull up the curriculum lesson file for your weakest one or two topics only (content/veridian/curriculum/wec14/) and re-read its trap-taxonomy section, not the full worked derivation again. FORGE §4 already indexes which lesson covers which trap — use that index rather than re-reading all seven lesson files.
Do not start this block by opening a past paper cold. Re-reading first, testing second, is the order this whole document is built around.

#T-30 to T-14 — one full timed paper, marked against the real scheme's conventions

Sit one complete past paper under real timing: 2 hours, 80 marks. Use FORGE §1's timing budget while sitting it, not just to check afterwards — roughly 6–9 minutes on Section A, ~51 minutes on Section B (about 5 minutes reading the source booklet first), ~60 minutes on Section C (2–3 minutes reading all three prompts before choosing). A principal examiner states this directly, not as encouragement but as a documented feature of this specific paper: "most candidates were not actually able to complete the paper in the time available" (WEC14 Examiner Report, January 2025). Protect the second Section C essay specifically — FORGE §1 names Section B over-investment as the single most common cause of a rushed second essay.
Mark it against the real scheme if you have one, running FORGE §3's self-mark checklist line by line before you look at the scheme's own award of marks.
For every mark lost, sort it into one of two piles: (a) a genuine content gap, and (b) a presentation gap — you knew the economics but wrote it in a shape the mark scheme wouldn't credit (evaluation on the 6-mark part, a listed rather than developed KAA point, a bulleted essay, a copied extract sentence with nothing done to it). Pile (b) is what 48 hours can still fix — re-read the matching FORGE §2/§4 sub-section for each item. A pile-(a) item on a large, unfamiliar topic goes to §4 below rather than into a same-day cram.
If you don't have a second full paper for this block, don't manufacture pressure by re-sitting the same paper — you already know the answers. Use the extra time on §2 below instead.

#T-14 to T-8 — targeted self-test, no new material

Work through §2 below as a closed-book, no-notes retrieval test. Each prompt should take seconds, not minutes, if the fact is actually loaded.
For anything you can't answer from memory, look it up once, now — a one-line lookup is fine in this window; reconstructing a technique or a named model you never solidly had is not (§4).
Run §3's quantitative-and-definition recall drill once. The single most repeatable, cheapest loss on the whole paper is Section B Q7(a)'s 2 marks — genuinely costing candidates marks in a series where 70% still scored full marks and roughly 30% lost at least one (January 2025) — almost always a percentage-vs-percentage-point slip, not a maths error.

#T-8 to T-1 — wind down, light contact only

One short pass over your own error log from the timed paper (piles (a) and (b)) — recognition, not new practice. If you're re-solving full essay questions in this window, you've moved back into T-14–T-8's territory; stop and switch to recognition-only review.
Confirm exam logistics now: candidate number, exam location/time, permitted equipment, and (unlike WEC14's own calculator-free maths siblings) that you know which quantitative-skills calculations (index numbers, percentage-point changes, the Gini area ratio) you can do reliably by hand under time pressure, since QS1–9 are a minimum of 20% of this unit's marks (facts bank, Assessment structure).
Sleep. This document cites no source for that because none of this course's research is about sleep — it's ordinary judgement, not a WEC14-specific finding.

#T-1 to T-0 — morning of, before you walk in

Re-read §3 (recall drill) once, from memory, out loud or on paper.
Re-read FORGE §5's exam-day protocol once — this document does not repeat it here, to avoid the exact restatement this task was told to avoid. The one line worth holding in your head walking in: stop Section B at the deadline even mid-answer, because a rushed second Section C essay typically costs the entire informed judgement, worth several marks on its own.
Do not attempt a new past paper, a new topic, or a new practice question in this window.

#2. Self-test: retrieval prompts built from real, recurring losses

Answer each from memory, in under 30 seconds, before checking the source. Every prompt below is built from a real, cited finding already established in the facts bank or FORGE — none is invented for this document.

On Section B, which of the 4/6/8-mark parts do you write no evaluation on at all, and which two do? (No evaluation on the 6-mark "analyse/examine two" part — it earns nothing there. Evaluation is required on the 8-mark "examine two [problems/effects]" part and on Q7(e). Confirmed directly, four years apart: Jan 2021 Q7(b); Jan 2025 Q7(c)/(d) — FORGE §2.)
Neither half of Q7(e) can reach one particular level. Which, and what does that change about how you spend your time on it? (Level 4 — both the 8-mark KAA band and the 6-mark Evaluation band cap at Level 3. Because there's no "reach for Level 4" move available, cover exactly two points from the source and develop each, rather than chasing a fourth stage on one point or listing a third. Jan 2021 Examiner Report — FORGE §2.)
What's the real, four-series-confirmed ceiling on a KAA chain that only reaches "X causes Y, so Z happens" and stops? (Level 2 — a two-stage chain of reasoning, whatever topic it's on, doesn't reach Level 3 KAA. Confirmed on terms of trade and aid/development (Jan 2021), income inequality (Jan 2024), and named again in Jan 2025's general summary. A third/fourth stage ending in a named variable with a stated direction is what's actually credited. FORGE §4.)
A Section C essay asks you to evaluate a policy "for a developed economy." You write a strong answer but never name a country in the body. What's the real cap, and is the gate universal? (Capped at Level 3, 9 marks maximum — WEC14 mark scheme, January 2024, Q8. Not universal: it tracks the stem's own wording, and October 2023's Q8, worded generically as "a country," carries no such gate at all. Check the actual stem every time. Facts bank §"Section C country gate.")
You define a customs union as "free trade between member countries" and stop. How many of the two available marks do you get? (One. The credited definition has two required halves — free trade between members, plus a common external tariff on outsiders — and dropping the second half is the standard way this exact question is half-answered. Jan 2022 Q7(c) — facts bank §4.3.2.4.)
An essay asks for market-orientated strategies and you discuss infrastructure spending. What do you score for that paragraph, and why? (Zero — infrastructure investment is an interventionist strategy, and mark schemes explicitly credit nothing when the wrong category is argued, confirmed independently in two series: Jun 2024 Q7(e), Indonesia; Jan 2024's equivalent essay. Facts bank §4.3.6.)
Name the two named growth/development models candidates most often swap for each other, and in which direction each swap has been documented. (Harrod-Domar, the savings-gap model, and the Lewis dual-sector/industrialisation model. Documented both ways: Jan 2022 Q2 MCQ, candidates named Harrod-Domar when the answer was Lewis; Jan 2021 Q2 MCQ, the reverse. Facts bank §4.3.6.)
A source booklet describes a country needing outside financial help during a balance-of-payments crisis. Which two institutions are most often confused with each other, and which organisation is explicitly not one of them at all? (The IMF and the World Bank — flipped in Jun 2023 Q9 and separately confused with fiscal/monetary policy roles in Oct 2022 and Oct 2023. TNCs are explicitly not international institutions for this spec point; crediting TNC content here scores nothing. Facts bank §4.3.6.)
You define relative poverty as "income below the median." What real, citable failure rate does this produce, and why is the definition wrong on its own terms? (Only 6% of candidates scored full marks on this exact question, Jan 2021 Q7(c) — the sharpest single failure-rate statistic in the whole archive. It's wrong because exactly half of any population sits below its own median by construction, regardless of how unequal the distribution actually is; the real threshold is a stated fraction of the median, conventionally 60%. Facts bank §4.3.4; CODEX Part 1.)
A floating currency falls in value. What's the correct term, and what's the recurring wrong-vocabulary trap this exact scenario is built to catch? (Depreciation. Devaluation and revaluation belong only to fixed/managed regimes; depreciation and appreciation belong to floating ones. This confusion is deliberately built into MCQ distractors and flagged in at least four series — Jan 2021, Jan 2022, Oct 2020. Facts bank §4.3.3.)
You copy a sentence directly from the source extract into your Q7(e) or 8-mark answer without adding anything to it. Does it earn an analysis mark? (No — confirmed on both the 8-mark Section B part and Q7(e), across five years: Jan 2021 Q7(d); Jan 2025 Q7(d) and Q7(e). A sentence that would be exactly as true with the source booklet closed earns nothing for analysis.)
You write four evaluation points on a Section C essay but never state a final verdict. What level does that cap you at, no matter how many points came before it? (Level 2. Reaching Level 3 evaluation specifically requires a stated, informed judgement — a verdict plus the condition it depends on — confirmed in near-identical wording four years apart, Jan 2021 and Jan 2025. Quantity of evaluation points does not substitute for the judgement itself. FORGE §4.)

If more than two or three of these take longer than 30 seconds, that's real, specific information about where the remaining hours should go — reread the cited lesson file's trap section for that item, not the whole file.

#3. Quantitative-skills and definitions recall drill

WEC14 has no formula booklet entry to fall back on for any of the below — every one of these has to come from memory or be derived on the page. Say or write each one before checking codex-definitions-and-application-bank.md Part 1:

Terms of trade index = (export price index ÷ import price index) × 100, against a common base year. A rise is "favourable" on price terms alone — it says nothing by itself about export revenue, the trade balance, or living standards, because none of those are price-only questions.
The percentage-vs-percentage-point rule, out loud: a rate moving from 4% to 3.5% is a fall of 0.5 percentage points, not "0.5%." This single distinction is the most-repeated numerical error on the whole paper — flagged on national-debt calculations, tax-rate changes and interest-rate changes across at least five separate series.
Gini coefficient = Area A (between the line of equality and the Lorenz curve) ÷ Area (A + B) (the whole area under the line of equality). Practise reading the direction of a shift, not just the definition — a falling Gini coefficient means the Lorenz curve moves closer to the line of equality, and this direction is the specific thing repeatedly read backwards on real papers.
Marshall-Lerner condition: a devaluation/depreciation improves the trade balance in the long run only if PEDx + PEDm > 1. Pair it with the J-curve: the trade balance typically worsens before it improves, because the price effect is immediate and the volume response lags.
Laffer curve, in one sentence: tax revenue is zero at both a 0% rate and a 100% rate, so it rises over some range of rates and falls over another — a rate already past the revenue-maximising point can be cut with revenue rising, not falling.
Fiscal deficit vs national debt, said as a pair: the deficit is a flow (this year's shortfall between spending and tax revenue); the debt is the accumulated stock of every past deficit still owed. Confusing the two is a real, documented loss (Jun 2022 Q7(b)).

This drill is short on purpose — it is the set of things in this paper's quantitative-skills requirement (a minimum of 20% of the unit's marks) where "know it cold" and "roughly remember it" produce a different mark on the page, not just a different feeling of confidence.

#4. What NOT to start learning fresh in the last 48 hours

A named economic model you have never actually learned. Harrod-Domar (the savings gap), the Lewis dual-sector model (industrialisation), and Prebisch-Singer (primary-product terms of trade) are real spec content, genuinely rewarded when correctly cited, and — per §2 above — genuinely confused with each other under exam pressure even by candidates who do know them. Forty-eight hours is enough to drill which model is which (that's what the retrieval prompts above are for) — it is not enough to build a first understanding of a model's actual mechanism from zero and expect it to hold up in a 20-mark essay. If one of these is genuinely new to you this late, accept the risk on that specific question rather than spending several of your remaining hours on it.

4.3.2.4(d), conflicts between trading blocs and the WTO. This course's own research actively searched for a matching real question across 14 series and found none — not "under-counted," a genuine "not found" (facts bank, Flagged issues). There is no citable trap or technique to gain from building this sub-point fresh in your last 48 hours, because no primary source has yet shown what a real question on it rewards. If you don't already have it, the better use of the same hour is a re-read of terms of trade or balance of payments/exchange rates — both deeply tested (8 of 14 and 10 of 14 series respectively) and both carrying real, drillable traps in §2 above.

Public expenditure's capital/current/transfer-payment distinction, if it's genuinely new to you. The 14-series archive found no standalone question testing this sub-point on its own; the one real anchor (June 2025's Italy essay, Q10) sits outside that count. The three terms themselves are a five-minute definitional read (CODEX Part 1) — that's a fair use of the T-14–T-8 lookup window. Building fresh essay-level fluency with the Italy KAA/Evaluation content from scratch is not; use the application-bank entry for it directly (CODEX Part 2) rather than deriving your own version under time pressure.

A grade-boundary number as a target. Real, Pearson-published boundaries do exist for this paper (signal-frequency-and-boundaries.md §2, verified directly against Pearson's own grade-boundaries PDFs) — across ten series, A* has ranged 56–61 out of 80 and the minimum pass (E) 26–36 out of 80. That document states this as a range only, with no analysis of cohort size or paper difficulty behind it, and this document repeats that caution deliberately: don't let a specific target mark decide how the last 48 hours get spent. There is a real range to know your paper's history sits inside; there is no real prediction inside it.

Re-deriving your own revision notes from the curriculum files a second time. If you already built a summary earlier in the course, trust it in this window rather than rebuilding it from content/veridian/curriculum/wec14/ again "to be thorough" — that's re-reading disguised as new work, and it belongs in the T-48–T-30 block, not repeated in every later block too.

#5. Flagged gaps and honest limits

This document's factual claims are only as good as the series they trace to. 14 series have a fully-read question paper and mark scheme (October 2020–January 2025); 13 of those also have a matching examiner report (June 2021's is missing from the archive and cited nowhere above). A narrower, later pass separately checked isolated questions from a June 2025 mark scheme (Q7(a)/(b)/(d) and Q10) — real findings, but not counted in any "of 14" or "of 13" figure above, matching the facts bank's own convention.
No frequency claim above is a prediction. "Seen in N of 14" or "N of 13" (§1, §4) means a confirmed instance exists in that many series actually read — not that the same sub-point is N/14 likely to appear again this series. signal-frequency-and-boundaries.md §1 makes this same point about its own table, and this document inherits the caution rather than restating new evidence for it.
This document does not contain, and will not manufacture, a likelihood percentage for any topic appearing, or a new grade boundary. §4 states plainly what real boundary data exists and how little it licenses.
The self-test in §2 draws only on findings already named in the facts bank or FORGE — it introduces no new trap discovered specifically for this document. The addition this document makes is the retrieval-practice framing and the 48-hour time structure, not new underlying content.
The T-48-to-T-0 block structure and its specific hour ranges are this document's own judgement, not a cited finding — no WEC14 examiner report or spec document makes a claim about optimal revision timing, and none should be read into the section headers above.
