Cambridge Exam Strategies & Techniques

How examiners award marks for AO1 (Knowledge), AO2 (Application), AO3 (Analysis), and AO4 (Evaluation).

The "BLT" Formula (AO3 Analysis)

The most common examiner critique is that students write isolated statements without building analytical chains.

B - Because: State the core reason or business action.

L - Leads to: Explain the operational consequence in the business.

T - Therefore: Conclude with the direct effect on profit, revenue, or cash flow.

Decoding Command Words

State / Identify: 1 mark. A single word or short phrase. Do not write full paragraphs.
Explain: 2–4 marks. State your point, apply context (AO2), and explain one consequence (AO3).
Consider / Recommend: 6–12 marks. Balanced arguments covering both perspectives, finished with a justified verdict.
