WJEC A level grade boundaries June 2025

In Wales, WJEC reports every A level and AS unit on a uniform mark scale (UMS). The scale for the whole qualification is set out in the overall UMS document, and WJEC states on its grade boundaries page that UMS boundaries stay the same every year. So the totals below also describe 2026.

Qualification	Max	A	B	C	D	E
AS, most subjects	200	160	140	120	100	80
A level, most subjects	500	400	350	300	250	200
AS Maths and Further Maths	240	192	168	144	120	96
A level Maths and Further Maths	600	480	420	360	300	240

The A* rule

A* is an A level grade only. WJEC's grading rules award it to a candidate who has an overall A and at least 90% of the uniform marks on the A2 units, which is 270 in a 500-mark subject. For Maths and Further Maths that is 324 out of 360, per the Further Maths specification.

Unit raw mark boundaries 2025

A unit's raw marks are turned into uniform marks by the board, and the raw mark that earns each grade is published in WJEC's grade converter. The table copies the 2025 figures for our six subjects. The last column is the number of raw marks between an E and an A on the unit, a rough sense of how wide the grade range is.

Unit	Max UMS	A	B	C	D	E	A minus E
Biology AS Unit 1	100	47	40	33	26	19	28
Biology AS Unit 2	100	41	35	29	24	19	22

Further Maths Unit 4 has the widest range, 55 raw marks from an E at 36 to an A at 91, which fits a paper worth 210 uniform marks. The narrowest is Biology Unit 5 (35 for an A, 22 for an E, a gap of 13), a practical unit worth 50.

A worked A* check

Suppose a Biology candidate lands exactly on the A boundary of every unit in 2025: raw marks of 47, 41, 53, 48 and 35. The converter gives 80, 80, 100, 100, 40 uniform marks, a total of 400. That is an A. The A2 units (Units 3 to 5) contribute 240, and the A* rule needs 270, so the candidate is 30 uniform marks short of an A*.

The rule means a strong AS and an average A2 cannot produce an A*. The proof has to come from the A2 units.

What the 2025 results looked like in Wales

Senedd Research, using provisional JCQ data, reports that in Wales in 2025, 10.5% of A level entries were A*, 29.5% were A* or A, 77.2% were A* to C and 97.5% were A* to E. The A* share was 0.4 percentage points above 2024.

Reading the table as a student

Do not read a raw mark as a percentage. The raw mark for an A is less than the paper's total, and it changes from one summer to the next.
Think in uniform marks. To reach 350, a B, you need an average of 70% of each unit's uniform marks.
Check the unit, not the subject. A Physics Unit 3 A needed 74 raw marks in 2025, and a Physics Unit 5 A needed 41. The units carry different weights.
Keep the Eduqas boundaries apart. Eduqas A levels are sat in England, with their own components and grade points.

Turn today's paper into a rough guide

Try one of our A level papers. Each has 8 questions worth 25 to 35 marks, written by us and not by WJEC. For a pointer, line your score up with the UMS shares: 80% for an A, 70% for a B, 60% for a C, 50% for a D and 40% for an E. Treat it as a pointer, since a real unit converts its raw marks its own way.

Common questions

What were the WJEC A level grade boundaries in 2025?

The UMS totals: 400 for an A, 350 for a B, 300 for a C, 250 for a D and 200 for an E out of 500. In Maths and Further Maths, 480, 420, 360, 300 and 240 out of 600. The raw marks for each unit are in the table above.

What raw mark did an A need in WJEC A level Chemistry Unit 3 in 2025?

49. In 2026 it needed 39.

Is there an A* at AS in Wales?

No. A* is awarded at A level only, and AS goes from A down to E.

What is UMS?

A uniform mark scale. Each unit's raw mark is converted onto it so the same standard earns the same uniform mark whenever the unit is sat.

Are WJEC and Eduqas A level boundaries the same?

No. Eduqas is the England brand and publishes its own grade points for its own components.

Where does WJEC publish A level boundaries?

The UMS totals are in its overall UMS document and the raw marks for each unit are in its grade converter. Results day in 2025 was Thursday 14 August.
