Whether you are sitting GCSE, IGCSE or another school mathematics exam, the preparation that works is the same: master the fundamentals, practise under timed conditions, and fix your error patterns before exam day. This is a realistic plan, not a miracle cure.
Start with a topic audit
List every chapter in your syllabus and rate yourself honestly: confident, shaky, or lost. Most students find the list splits roughly into thirds. Your study time should go in reverse order — the "lost" third gets the most hours, because that is where the marks are hiding.
Begin with algebra: it underpins everything else. If rearranging equations and factorising feel automatic, every other chapter gets easier.
The six-week structure
- Weeks 1–3: rebuild. Work through your "lost" and "shaky" chapters, one at a time. Use worked examples actively — attempt first, then compare.
- Weeks 4–5: past papers. Two full papers per week under timed conditions. Keep an error log of every lost mark.
- Week 6: targeted repair. No new papers. Revisit only the error patterns in your log.
Using past papers properly
A past paper is a diagnostic tool, not a lottery ticket. After marking:
- Categorise every error: knowledge gap, method slip, or exam technique (time, misreading).
- Knowledge gaps go back into your rebuild list.
- Method slips get five similar questions the same day.
Students who do this typically gain a full grade between their first and last practice papers.
The final week
- Sleep beats cramming. A tired brain cannot do algebra.
- Skim your error log, not the whole textbook.
- Prepare the practical things: calculator (with fresh batteries), pens, ID, the exam timetable.
- The night before, do thirty minutes of easy questions you can already solve. Walk in having succeeded at maths recently.
