The Last Month IGCSE Maths Revision Plan
The final month before Cambridge IGCSE Maths exams is the most critical preparation period. What you do — and what you avoid — in these four weeks determines whether exam day feels familiar or frightening.
Week 1: Error Audit and Topic Focus
Start by marking your most recent full past paper and listing every question you lost marks on. Categorise by topic. Pick the top 3 topics by marks lost — these are your Week 1 focus. No new topics this week; only topics from your error audit.
Tips
- Mark your last full paper with the official mark scheme
- List every error and categorise by topic
- Spend Week 1 only on your top-3 error topics
Week 2: Targeted Practice + Timing
Spend Week 2 doing 20-question topic-specific sets from Cambridge past papers for each of your 3 focus topics. Time each set at 1 minute per mark. Review errors after each set. If a topic is resolved, move to the next highest-error topic from your Week 1 audit.
Tips
- 20-question topic sets, timed
- Review every error against mark scheme
- Move to next topic when error rate drops below 20%
Week 3: Full Papers Under Exam Conditions
In Week 3, do one complete Paper 2 and one complete Paper 4 under full exam conditions — no phone, no pausing, real timing. Mark with the official mark scheme. Focus your final coaching sessions on whatever Paper 4 Section B topics caused errors.
Tips
- Paper 2: 1hr 30min, no calculator, no interruptions
- Paper 4: 2hr 30min, calculator, real exam conditions
- Mark with official Cambridge mark scheme only
Week 4: Consolidation Only
Final week: do not introduce any new content. Review mark-scheme answers for your recurring error types. Practice Paper 4's final 20 marks section — most students run out of time here. Ensure sleep, food, and travel logistics are planned. Read your question and answer booklets the night before.
Tips
- No new content in the final week
- Practise the final 20 marks of Paper 4 for timing
- Sleep and logistics planned before exam week
Key Takeaways
- Week 1: error audit, Week 2: targeted sets, Week 3: full papers, Week 4: consolidation
- Final week: no new content
- Paper 4 final section timing must be practised explicitly

What if I discover a major gap in Week 3 or 4?
In Week 3, one tutoring session on the gap is appropriate. In Week 4, do not attempt to learn a new topic from scratch — focus your limited time on consolidating what you already know. Partial marks on familiar topics are better than zero on a new one.
How many hours per day should I revise in the final month?
2–3 hours of focused practice per day is optimal. More than this produces diminishing returns and risks mental fatigue before exam day.
