Diagnostic Framework — Requires Real Practice Paper Input
Not affiliated with or endorsed by Pearson Edexcel.
HOW TO USE THIS
Complete a full WEC12 practice paper under timed conditions (105 minutes). Use this framework to diagnose where marks are being lost and in what order to prioritise fixes. Do NOT use this without a real scored practice paper — the scores require actual examiner feedback or self-marking against the mark scheme.
STEP 1 — SCORE YOUR PAPER
| Section | Your marks | Maximum | Gap |
|---|---|---|---|
| Section A — MCQ | /6 | 6 | |
| Section B — Q7 | /4 | 4 | |
| Section B — Q8 | /4 | 4 | |
| Section B — Q9 | /4 | 4 | |
| Section B — Q10 | /4 | 4 | |
| Section B — Q11 | /4 | 4 | |
| Section C — Q12a | /2 | 2 | |
| Section C — Q12b | /4 | 4 | |
| Section C — Q12c | /6 or 8 | 6 or 8 | |
| Section C — Q12d | /8 or 6 | 8 or 6 | |
| Section C — Q12e | /14 | 14 | |
| Section D — Q13/14 | /20 | 20 | |
| TOTAL | /80 | 80 |
STEP 2 — IDENTIFY YOUR FAILURE PATTERN
For each section where you lost 2+ marks, identify the cause from this list:
SECTION B FAILURE PATTERNS
| Pattern | What it looks like | Fix document |
|---|---|---|
| Draw: wrong axis labels | "Price" not "Price level" / "Output" not "Real output" | F9, N13 |
| Draw: missing dotted lines | Equilibrium point only, no lines to axes | F9, N13 |
| Draw: written text alongside diagram | Text present on a Draw question | F11 |
| Explain: chain-short | Four sentences but Stage 4 missing | F2, N11 |
| Explain: data standalone | Extract figure quoted separately not embedded | N10, N5 |
| Calculate: no working shown | Only final answer, no formula/steps | F11 |
SECTION C Q12a FAILURE PATTERNS
| Pattern | Fix |
|---|---|
| 1/2: qualifier missing (circular/informal) | F1, T3-26 |
| 1/2: causes added (irrelevant) | F1 |
| 0/2: completely wrong term | T3-26 |
SECTION C Q12c/d FAILURE PATTERNS
| Pattern | Mark impact | Fix |
|---|---|---|
| Chain-short (Stage 3 endpoint) | −1 to −2 marks | N11, F2, F3 |
| Data standalone (not embedded) | −1 mark per chain | N10 |
| Evaluation on 6-mark | 0 marks + time wasted | N5, F2 |
| Solutions on 8-mark | 0 AO4 marks | N5, F3 |
| Only one chain | Level 1 KAA | F2, F3 |
SECTION C Q12e + SECTION D FAILURE PATTERNS
This is where the biggest mark gaps are for most students.
| Pattern | Mark impact | Fix document |
|---|---|---|
| Unconditional conclusion | Level 2 eval cap (−2 to −3 eval marks) | N6, N12 |
| P2 missing (bilateral development) | Level 3 KAA ceiling + 1–2 eval marks | R2, N6 |
| Chain-short on both chains | Level 2 KAA (−3 to −6 KAA marks) | N11, N6 |
| Own-country data absent | Context ceiling Level 3/2 max | N10, R6 |
| Data bolted on (not embedded) | Partial AO2 credit only | N10, N5 |
| Judgement restates body | Level 3 mid not top (−1 eval mark) | N12, N3 |
| Evaluation at end (not after each chain) | Level 2 eval structure | R1, R2 |
| Same mechanism on both chains | Bilateral test fails = Level 2 | R1, F7 |
| Generic evaluation ("time lag" alone) | Level 1 eval (−3 to −4 eval marks) | N2, N12 |
| Unconditional evaluation sentences | Level 2 eval maximum | N5, N12 |
STEP 3 — PRIORITISE YOUR FIXES
Rank your failure patterns by mark impact (largest gap first). Use the fix documents in this order:
HIGHEST MARK IMPACT (fix first):
- Unconditional conclusion → N12 drill, then N6 threshold guide
- P2 missing → R2 Part 5 (four-paragraph structure) and worked P2 example
- Chain-short → N11 chain completion drill (25 seconds per chain)
- Own-country data missing → R6 application bank, N10 training manual
MEDIUM IMPACT: 5. Data bolted on → N10 five-step embedding process 6. Evaluation at end not after chain → R1 Part 4 placement rule 7. Generic evaluation → N2 definitive evaluations guide
LOWER IMPACT: 8. Axis labels → N13 diagram drill (memorise once) 9. Definition qualifier → T3-26 definition masterlist
STEP 4 — TARGET MARKS
| Grade boundary (estimate) | Total marks |
|---|---|
| A* | 64+ /80 |
| A | 56–63 /80 |
| B | 48–55 /80 |
| C | 40–47 /80 |
To move from current to target:
Most mark gains come from two habits: adding Stage 4 to chains (25 seconds each, +1–2 marks per chain) and adding "only if [condition]" to conclusions (20 seconds, +1–2 marks per conclusion). These two habits alone typically add 4–8 marks to a full paper.
