How to get an A at AS and an A* in Edexcel International A Level Economics

Organise the course around economic problems

Pearson IAL Economics has four units. AS covers markets in action and macroeconomic performance and policy; A2 adds business behaviour and developments in the global economy. Confirm the specification and format used for your examination entries.

Create a map linking a problem to possible explanations and policies. Inflation may involve demand, costs or expectations; unemployment can have different causes requiring different responses. A2 adds depth, but earlier ideas remain useful. Keep revisiting elasticity, opportunity cost and the transmission of policy while learning more advanced firm and international analysis.

Make the mechanism explicit

Write each important step between the initial change and the final outcome. If interest rates rise, explain how borrowing costs or saving incentives may change expenditure before concluding what could happen to aggregate demand. Avoid jumping straight from a policy to a desired result.

Use the question’s context to select the most relevant chain. A policy may affect households, firms and government differently. When time is limited, develop the strongest routes rather than listing every possible consequence. Check that the direction of each link is consistent and that you have not quietly changed the assumption halfway through.

Make diagrams do analytical work

Choose a diagram because it represents the mechanism you are explaining. Label axes, curves, initial and new equilibria where relevant. In your prose, refer to the movement or shift and explain what causes it. A correct diagram that is never discussed leaves part of the reasoning unstated.

Practise drawing from a written scenario rather than copying a page. Separate a movement along demand from a shift of demand, and a change in a price index from a change in the inflation rate. At A2, apply the same care to market structures, costs and international relationships.

Use conditions to reach a judgement

Good evaluation identifies why the size or direction of an effect may differ. Consider elasticity, spare capacity, confidence, time lags, policy scale or the quality of institutions when those factors are relevant. Explain the condition’s effect rather than adding a disconnected list of limitations.

Use data carefully: distinguish levels from rates of change and percentage points from percentages. A conclusion should answer the question and weigh the strongest evidence. It can acknowledge uncertainty while still making a reasoned judgement. During revision, practise changing one assumption and explaining how your conclusion would change.

Common mistakes—and how to fix them

Your four-week revision plan

Use this as a focused revision cycle alongside your lessons. If you are still learning the course, give unfamiliar topics more time before attempting full papers.

1. Week 1

   Check foundations

   • Retrieve definitions and draw core diagrams from scenarios.
   • Identify weak microeconomic and macroeconomic chains.
2. Week 2

   Develop application

   • Use supplied data to support two-stage and three-stage explanations.
   • Practise percentage changes and elasticity interpretation.
3. Week 3

   Strengthen judgement

   • Evaluate the same policy under different conditions.
   • Write conclusions that weigh evidence instead of repeating paragraphs.
4. Week 4

   Rehearse and refine

   • Complete timed data questions and essays from your entered units.
   • Review diagram accuracy, context and the weakest link in each argument.
