What is it?
Past papers show you the style, wording and difficulty of real exam questions. Used well, they are a form of practice testing, one of the study techniques that research rates as most useful.
The learning happens in the review. Marking your work against the mark scheme and understanding exactly why you lost marks matters more than doing many papers.
Key formulas and ideas
- Plan: use papers from your own exam board and the current specification.
- Do it: work under realistic conditions, with the time limit and no notes.
- Mark it: use the official mark scheme, and be strict.
- Review: record every lost mark, find the cause and fix it, then retry similar questions later.
Worked examples
Example 1: Timing
Question: A paper has 80 marks and lasts 90 minutes. How long per mark?
- 90 ÷ 80 = 1.125 minutes per mark.
- Leave some time to check your work.
Answer: About 1 minute per mark
Example 2: Error analysis
Question: You lose 3 marks on a question. How do you review?
- Compare your answer with the mark scheme.
- Decide the cause: knowledge gap, misread question, wrong method or lack of detail.
- Write the correct answer in your own words.
Answer: Identify the cause and rewrite the correct answer
Example 3: Build up
Question: When should you start full papers?
- First revise the topics and practise short questions.
- Then attempt sections of papers.
- Finally do full timed papers closer to the exam.
Answer: After you have revised the content
Common mistakes
- Reading the mark scheme before attempting the paper.
- Marking too generously.
- Doing papers without reviewing mistakes.
- Using up all the papers too early.
