How to use past papers properly for GCSE revision
On this page
A pupil who does ten past papers, glances at each score and moves on learns less than one who does three and studies every lost mark. The learning happens in the marking.
This guide is for Year 10 and 11 pupils, and for parents who want to help without needing to know the subject.
Finding the right papers
Each GCSE subject is set by an exam board. In England the main ones are AQA, Pearson Edexcel, OCR and WJEC Eduqas. Ask your teachers which board and which specification you are taking in each subject, because papers from another board, or an older specification, can cover different content.
For each exam series the boards publish three useful documents:
- the question paper
- the mark scheme, showing what earns credit
- the examiner's report, explaining how candidates actually answered and where marks were commonly lost
The examiner's report is the most neglected of the three and often the most useful. The most recent papers are sometimes held back for a period so schools can use them as mocks; if you cannot find one, ask your teacher. For new specifications with few past papers, boards publish specimen papers and sample assessment materials.
When to start
Past papers work best once the content has been taught. A whole paper in early Year 10 mainly tells you what you have not covered yet.
- Year 10 and early Year 11: single questions on topics you have finished in class.
- From the mocks onwards: full papers in timed conditions.
- Final weeks: a mix of full papers and targeted questions on weak topics.
Three ways to use a paper
Topic questions. Pull questions on one topic from several papers. This suits a single revision block and works as retrieval practice, which our guide to quizzes and retrieval practice explains.
Full timed papers. Same time as the real exam, no notes, phone in another room. This builds stamina and shows how well you manage time. A useful check is time per mark: a paper worth 80 marks in 1 hour 30 minutes gives a little over a minute per mark, so a 6-mark question deserves around six or seven minutes, not twenty.
Mark scheme study. Skip the answering. Read a question and its mark scheme side by side and ask what exactly the examiners wanted. This is especially useful for extended answers in English, history and the sciences, where structure matters as much as facts.
Marking strictly: a walkthrough
Mark with the official mark scheme and be honest. If it wants a particular idea and you wrote something vaguely similar, the mark is not yours.
Here is a 2-mark science-style question:
Explain why a metal spoon feels colder than a wooden spoon when both are at room temperature.
Answer A: Metal is colder than wood.
Zero marks. Both spoons are at the same temperature; that is the whole point of the question.
Answer B: Metal is a better conductor.
One idea, but no link to what you feel. One mark at most.
Answer C: Metal is a better thermal conductor than wood, so it transfers energy away from your hand more quickly, which makes it feel colder.
Two marks: the comparison of conductivity, and the faster energy transfer from the hand. Comparing B and C teaches more than three new questions would. Notice that the command word was explain, which needs a reason, not just a statement.
Command words
| Command word | What it usually wants |
|---|---|
| State / Give / Name | A short answer, no explanation |
| Describe | What happens or what something is like |
| Explain | Why or how, with reasons |
| Compare | Similarities and/or differences, referring to both things |
| Evaluate | Points for and against, then a judgement |
| Calculate | A numerical answer, with working shown |
Boards publish their own command word lists with definitions, and they differ slightly between subjects, so check your board's version.
The mistake log
After marking, write every lost mark into a table.
| Paper and question | Topic | Why marks were lost | Next step |
|---|---|---|---|
| Maths Paper 2, Q14 | Simultaneous equations | Sign error when subtracting | Five more, checking signs |
| Biology Paper 1, Q6 | Osmosis | Described but did not explain | Practise "explain" answers |
| History Paper 1, Q4 | Causes of the First World War | Ran out of time | Use time-per-mark |
After a few papers, patterns appear. Lost marks clustered in one topic need more revision of that topic. Lost marks from misreading need a change of technique, such as underlining command words. Lost marks from timing need more full timed papers. Each of those belongs in your revision timetable.
Habits that waste papers
- Starting full papers before the content has been taught.
- Generous marking.
- Peeking at the mark scheme while answering.
- Only doing subjects you like; the most useful papers are usually the ones you are avoiding.
- Never looking back at a marked paper.
- Ignoring timing, which can cost more than any single topic gap.
Try it: This week, take one paper in a subject you find hard. Sit it timed, mark it strictly, read the examiner's report, fill in the mistake log and schedule the top two problems into next week. A week later, try the questions you got wrong again without looking.
Frequently asked questions
How many past papers should I do?
There is no magic number. A few full papers per subject, done properly, plus many single questions, is a good target. Quality beats quantity.
How can a parent help without knowing the subject?
Set the timer, keep the space quiet, and afterwards ask your child to explain one thing they learned from the mark scheme. Leave the marking to them or their teacher.
Past papers make me panic. What should I do?
Start with single questions rather than whole papers and build up slowly. Our guide to helping with exam nerves has techniques that work in the exam room too.
