WJEC A-level Maths grade boundaries 2026: raw marks and the 600 scale

WJEC A-level Maths grade boundaries June 2026

Maths (1300) is graded on a 600 scale, as WJEC's overall UMS document says. Its four units are Pure Mathematics A and Applied Mathematics A at AS, then Pure Mathematics B and Applied Mathematics B at A2, according to the specification, and they are worth 150, 90, 210 and 150 uniform marks. A2 Unit 3 alone is 35% of the grade.

Raw marks per unit, 2026

These raw marks are from the 2026 grade converter.

A worked total

A candidate scores 68, 46, 70 and 44 raw marks in Units 1 to 4. The converter gives 113, 68, 159, 111 uniform marks, a total of 451 out of 600. That clears the B boundary of 420 and is 29 short of the A boundary of 480. The A2 units give 270 of the 360 available, and an A* needs 324.

The Unit 3 jump

A2 Unit 3 asked for 10 more raw marks for an A in 2026 (75 against 65), 9 more for a B, 8 more for a C, 7 more for a D and 6 more for an E. Unit 1 went the other way, from 79 down to 74 for an A. Because Unit 3 is worth 210 uniform marks, its boundary matters most for the A level grade.

Senedd Research notes that Maths remained the most popular A level in Wales and entries rose by 202 (5.3%) in 2026.

The size of the Unit 3 swing is easy to under-estimate. A candidate with 70 raw marks on Unit 3 gets about 159 uniform marks in 2026, which is 76% of the unit. In 2025 the same 70 marks would have been worth more, since the A was only 65. A year-on-year comparison of raw marks is not a comparison of ability.

Planning with the 2026 numbers

• Think in 600. An A overall is 80% of 600, the same share as other subjects but a bigger number.
• Unit 3 and Unit 4 hold the A*. They give up to 360 uniform marks, and an A* needs 324 of them.
• AS Unit 2 moved up slightly. An A needed 49 raw marks, up from 47.
• Do not plan on last year's Unit 3. It moved by 10 marks.
