OCR A-level Maths grade boundaries 2025: Mathematics A and MEI

OCR A-level Maths grade boundaries 2025

The numbers are from OCR's June 2025 A Level boundaries document (version 1.0, published 14 August 2025). OCR runs two Maths A-levels with different papers, so each has its own column. A boundary is the minimum total mark for the grade, and the total is the sum of all three papers.

Our OCR A-level Maths guide covers the H240 papers, and the board-wide OCR A-level boundaries for 2025 list the other subjects.

Paper by paper, 2025

Mathematics A has three papers of 100 marks. In the MEI course the third paper is Pure Mathematics and Comprehension, out of 75. OCR's notional paper boundaries are for information, and they show where the marks were hardest to find.

On Mathematics A, Paper 1 (pure) needed 84 for an A*, Paper 2 (pure and statistics) needed 83 and Paper 3 (pure and mechanics) needed 75. The mechanics paper was the hardest to score on. In the MEI course the mechanics and pure paper needed 89 against 76 for the statistics paper.

How 2025 compares with 2024

Mathematics A rose at every grade. The A went from 168 to 196, the C from 106 to 130 and the E from 44 to 64. The 2024 boundaries were unusually low, with an E at only 44 out of 300, which is 15%, and they are in OCR's document of 15 August 2024. In MEI the movement was mixed: A* fell by 5 while grade B rose from 156 to 159.

Ofqual says boundaries vary from year to year to reflect the difficulty of each paper. A 26 mark rise at A* is large, and it means the 2025 Mathematics A papers were easier to score on than those of 2024.

AS Maths boundaries 2025

The AS qualifications are separate, have no A*, and are sat on their own. Mathematics A (H230) is out of 150 and Mathematics B, MEI (H630) is out of 140.

Marks to grade: two Maths examples

• Mathematics A. A candidate scores 79, 68 and 60 on the three papers, so 207 out of 300. That is above 196 (A) and below 242 (A*), so the grade is an A, 35 marks short of an A*. In 2024 the A* line was 216, so the same total would have been still an A, only 9 marks short.
• Mathematics B (MEI). 69, 61 and 52 (the last out of 75) make 182 out of 275. The A line is 190 and the B line is 159, so the grade is a B, 8 marks short of an A.

OCR explains the method in How do we calculate your A Level grade?: component marks are added, then the total is checked against the boundaries.

Advice for A-level Maths from the 2025 numbers

• Pure carries most of the marks. Every paper includes pure maths, so pure fluency pays on all 300.
• Do not rely on a low boundary. The Mathematics A grade E moved by 20 marks in a year.
• Mechanics deserves time. It was the paper with the lowest notional boundaries, so it was the hardest to score on.
• Calculators are allowed. Practise with the calculator you will use in the exam.

Practise with today's A-level Maths paper

Today's short papers cover algebra and functions, calculus, statistics and mechanics. Each has 8 questions, so they are timed checks on technique, not OCR papers. Mark one and convert it to a share: the Mathematics A grade A was 65% in 2025 and the A* was 81%.
