Getting an A* in A-Level Maths feels mysterious from the outside. You see the people who get one and assume they were simply "good at maths". Almost always, that is wrong. The A* is the most learnable top grade of any A-Level, because maths is a closed skill: there is a finite list of techniques, the questions reward method over flair, and the mark scheme is ruthlessly predictable.
This guide breaks down exactly what an A* requires and how to build the habits that get you there — whether you sit Edexcel, AQA or OCR.
First, understand what the A* actually demands
For Edexcel, AQA and OCR, the headline rule is the same:
- You need an A overall across your three papers (typically 80%+ of the UMS-equivalent), and
- An average of 90%+ across the two A2 papers specifically.
That second condition is the one people miss. You can have a strong year and still slip the A* on the A2 average alone. The practical takeaway: the A2 content is where the A is won or lost.* AS topics matter, but the second-year material — further differentiation and integration, the binomial for any rational power, trig identities, parametric equations, vectors in 3D, Newton's laws — is where you must be near-perfect.
The A* is decided in the last 10%. Most students can comfortably reach 75–85%. The gap to 90%+ is almost entirely unforced errors and the hardest 2–3 questions per paper — both of which are trainable.
The mindset shift: marks are a system, not a verdict
A-Level Maths mark schemes award method (M), accuracy (A) and occasionally B marks for standalone results. This has two consequences that should change how you work:
- A wrong final answer can still score most of the marks if your method is visible and correct. Show every line.
- A right answer with no working can lose marks on "show that" and longer questions.
A* students write maths the way a mark scheme reads it. They make their method impossible to miss.
A revision routine that actually moves the grade
Passive revision — rereading notes, watching videos, highlighting — feels productive and does almost nothing for maths. Maths is a doing subject. Your routine should be built on three pillars.
