How to Get a Grade A in IGCSE Maths
A grade A typically requires around 155 out of 200 marks. You can afford to lose about 45 marks, but you must be solid across all major topics. This guide shows you how.
Mark Targets
Aim for at least 72 on Paper 2 and 83 on Paper 4. Focus on securing marks in your strongest topics first, then build confidence in weaker areas.
Tips
- Identify your three weakest topics and prioritise them
- Aim for full marks on the first half of each paper
- Do not leave any question blank
Key Topics to Secure
Grade A requires competence across algebra, trigonometry, statistics, and number. You do not need to master the very hardest questions but you must handle mid-difficulty questions confidently.
Tips
- Ensure fluency with simultaneous equations and quadratics
- Practise trigonometry in non-right-angled triangles
- Know how to interpret cumulative frequency and box plots
Reducing Errors
The gap between A and B is often careless mistakes. Develop a checking routine and practise under timed conditions to build accuracy.
Tips
- Re-read each question after writing your answer
- Check that your answer is a sensible size
- Practise full past papers under timed conditions weekly
Key Takeaways
- Target ~155/200 across both papers
- Secure all easy and medium marks first
