How to Get an A* in IGCSE Maths
An A* typically requires around 176 out of 200 marks across both papers. That means losing no more than 24 marks total. This guide explains exactly what it takes to reach the top grade.
Mark Targets
Aim for at least 85 on Paper 2 and 91 on Paper 4. You cannot afford to drop easy marks — accuracy on straightforward questions is just as important as solving hard ones.
Tips
- Target full marks on questions worth 1–3 marks
- Accept losing a few marks only on the hardest questions
- Practise until careless errors are near zero
Mastering Hard Topics
A* candidates must be confident with calculus, functions, vectors, and proof. These topics appear in the final questions worth the most marks.
Tips
- Dedicate extra revision to differentiation and its applications
- Practise composite and inverse function questions
- Work through vector geometry proofs step by step
Exam Technique for Top Marks
At A* level, the difference is often exam technique rather than knowledge. Precise notation, clear working, and careful checking separate A* from A.
Tips
- Use correct mathematical notation throughout
- Never skip steps in your working
- Check answers by substituting back into the original equation
