Working through a full exam paper can be useful, but it may not show you exactly which part of a subject needs more attention. Topic-based practice gives revision a sharper focus.
Find the gap behind a wrong answer
When you miss a question, identify the idea or step that caused difficulty. Was the concept unfamiliar, did you misread the question, or did a calculation go wrong? The answer guides what to revise next.
Practise, review, then return
Choose a small group of questions from one topic. Review your answers and explanations, revisit the learning material, then try a fresh set later. Returning to a topic helps check whether the understanding has stuck.
Use full tests to check readiness
Once you have worked through the important topics, timed practice can help you get comfortable with exam pacing and switching between question types.
A strong preparation plan uses both focused practice and full assessments. The balance can shift as the examination gets closer.
