✍️ 20-Mark Essay Practice
Structure: Intro → KAA1 (with diagram) → KAA2 → KAA3 → EVAL1 → EVAL2 → Conclusion. Aim for ~600–800 words. Discuss two agents and include a labelled diagram description.
Mark Caps: No diagram = max 9/12 KAA. Only one agent = max 9/12 KAA. No weighing up = max 6/8 Eval.

Select a question topic:

📋 Mark Scheme Reference
Total: 20 marks — KAA: 12 marks | Evaluation: 8 marks. Must discuss ≥2 agents and include a diagram for Level 4 KAA.
KAA Levels (12 marks)
Level 4 — 10–12 marks

Accurate, detailed analysis. Relevant diagram. Multi-stage chains of reasoning. Two agents discussed. Strong economic logic throughout.

Level 3 — 7–9 marks

Mostly correct analysis, some development. One agent or missing diagram caps at 9. Reasonable chains but may lack full depth.

Level 2 — 4–6 marks

Basic explanation of relevant concepts. Limited development. Some errors but broadly correct direction.

Level 1 — 1–3 marks

Simple statements or definitions. Little or no development.

Evaluation Levels (8 marks)
Level 4 — 7–8 marks

Detailed, developed evaluation. Considers significance, time period, context. Reasoned conclusion weighing both sides.

Level 3 — 5–6 marks

Some development of evaluative points. Attempts to weigh up. Conclusion present but limited.

Level 2 — 3–4 marks

Counter-arguments stated but not developed. Conclusion asserted rather than argued.

Level 1 — 1–2 marks

Superficial evaluative phrases only. No real development.
