How to Use Past Papers Properly: Why Doing More Is Not Always Better
Written by Ms. Fathima, Lead Teacher at Tandem Learner · 2 min read
Past papers are the closest thing to the real exam, which is why students and parents rely on them. But many students use them badly: they do a full paper early, see a low mark, and lose confidence without learning anything from it. Used well, past papers are one of the fastest ways to improve.
Start with topical questions, not full papers
In the months before the exam, practise by topic. Pick algebra, do ten questions from past papers on algebra, mark them, learn from the mistakes, and repeat. A full paper tests everything at once, so it hides which topic caused the lost marks. A topical set shows you straight away.
Use your own exam board's papers
Cambridge and Edexcel word their questions differently and structure their papers differently. Practise with papers from the board your child is actually sitting, so the wording, layout and command words feel familiar on the day.
Read the mark scheme like a teacher
After marking, do not just tick or cross. Read the mark scheme to see where each mark is given. You will notice that marks are often awarded for method, not only the final answer, and that answers need to be written in a certain way to earn credit.
- Which steps earn marks even if the final answer is wrong?
- What exact wording or units does the mark scheme expect?
- How many marks does this question carry, and how much working does that suggest?
Keep an error log
For every lost mark, write one line: the topic, what went wrong, and what the correct approach was. Review this log once a week. After a few weeks it becomes the most personal revision guide your child will ever have.
Save timed full papers for later
Closer to the exam, switch to full papers under real conditions: a quiet room, no phone, and the real time limit. This builds stamina and pacing. Do not use up every available paper early. Keep the most recent ones back for the final weeks.
A simple order that works
The aim is not to complete as many papers as possible. It is to learn something from every paper you do.
- First: fix gaps and rebuild topics
- Then: topical questions with mark scheme review
- Then: mixed topic sets
- Finally: full timed papers, marked strictly and logged
