AQA A-level Maths grade boundaries 2025: marks for A* to E

AQA A-level Maths grade boundaries June 2025

From the Mathematics Adv row of AQA's A-level grade boundaries for June 2025 (version 1.0, published 14 August 2025). Each figure is the lowest total out of 300 that earns the grade, and a total below the E boundary is a U.

The 300 is three papers of 100 marks, each carrying a third of the A-level. AQA's scheme of assessment says all three are marked with a scaling factor of 1 and that the qualification is linear, with every exam sat at the end of the course. Our guides to A-level Maths and AQA A-level Maths cover the content, and the formula booklet guide lists what you are given. Practice by topic: calculus, statistics and mechanics.

From three papers to a grade

Suppose you score 74, 70 and 77 on the three papers. That is 221 out of 300, which is exactly the A boundary of 221. A total equal to the boundary earns the grade, so it is an A. One mark fewer would have been a B, which needs 183. To reach A* you would have needed 39 more marks.

The A* boundary is 87%, which means the difference between an A and an A* in 2025 was 39 marks, about 13% of the marks. The step from A to B is 38 marks and from B to C 38.

2025 against 2024 and 2023

From AQA's 2024 and 2023 documents:

2023 stands apart: the A boundary was 201, then 222 in 2024, a rise of 21 marks. Between 2024 and 2025 the movement was tiny: A* up 1 to 260, A down 1 to 221, and C, D and E each down 2. The 2023 figures are much lower, so do not use them as a target.

AQA's paper-by-paper figures

AQA's document also lists notional boundaries for each paper, "for illustrative purposes only". They are not used to grade you, but they show how the three 2025 papers compared:

The three papers are close at every grade. At A, Paper 1 is 74, Paper 2 is 73 and Paper 3 is 74, so no one paper was markedly harder to score on than another. The grade comes from your total, never from a single paper.

What this means for A-level Maths revision

• An A* leaves 40 marks to lose. 260 out of 300 means you can lose about one mark in eight, so every mark on the last part of a long question counts.
• An E is 24%. 71 marks is under a quarter of the total, so a weak paper does not rule out a pass.
• An A is 74%. 221 marks. Aim for 75% on timed practice to leave a buffer.

Use today's paper to estimate your grade

Pick the algebra and functions, calculus, statistics or mechanics paper. Each is a short timed paper of 8 questions worth 25 to 35 marks, written by us and not by AQA, so it covers one area, not the whole A-level. Mark it, divide by the total, and compare with the shares in the first table. 22 out of 30 is 73%, which is one point under the A share. See A-level Maths mocks for how to use them as a mock.

Mistakes to avoid

• Treating one paper as the grade. The boundaries are for the total of 300.
• Using the notional paper boundaries to mark yourself. AQA says they are illustrative.
• Comparing with AS. AS is a different qualification with its own document.
