Edexcel A-level Maths grade boundaries 2025: every grade

Edexcel A-level Maths (9MA0) boundaries, June 2025

The figures are from Pearson's June 2025 GCE document. Mathematics is linear, so all three papers are sat in one summer and the total of 300 is read against the boundary.

The course is covered in our Edexcel A-level Maths guide, the formulae in the formulae booklet guide, and every subject in Edexcel A-level grade boundaries 2025.

The three 100-mark papers

The two pure papers draw on the same content, so they carry two-thirds of the total between them. The third paper splits statistics and mechanics. Calculators are allowed on all three.

How the 2025 lines compare with 2024

Here is Mathematics for June 2024 and June 2025:

The increase grew as the grade got lower: 7 at A*, 9 at A, 11 at B, 12 at C, 13 at D and 15 at E. AS Mathematics rose too, with grade A going from 105 to 108 and grade E from 47 to 57. Ofqual says grade boundaries typically change each year to reflect differences in the difficulty of the assessments, and that an easier paper gets higher boundaries.

Worked example

A student scores 71 on Paper 1, 66 on Paper 2 and 62 on Paper 3. The total is 71 + 66 + 62 = 199 out of 300. The 2025 lines are A 214 and B 178, so 199 is a B, 15 marks short of an A. In 2024 the same total would have been a B as well, but only 6 short of an A, because the A line was 205.

Add the three papers first, then find the highest line the total reaches.

AS Mathematics in 2025

AS Mathematics (8MA0) is a separate qualification out of 160, graded A to E. In June 2025 grade A needed 108, which is 68% of the total, and grade E needed 57, which is 36%. Compared with 2024 every AS line rose: A by 3, B by 5, C by 7, D by 8, E by 10. AS has its own table, so read it only for an AS entry and never against an A level total.

What the shares say

• An A* needed 86% of the marks and an A needed 71%.
• An E needed 24%. A student at that level has still earned a grade.
• Pure carries two papers of three. Weakness in algebra, calculus or trigonometry costs you on both.

To test yourself, use today's tracks: Algebra and Functions, Calculus, Statistics and Mechanics. Each is 8 questions and 25 to 35 marks and not an Edexcel paper, so turn your mark into a share and compare it with the table.
