WJEC A-level Computer Science grade boundaries June 2025
WJEC's Computer Science units do not share one weight. Unit 1 is out of 125 uniform marks, Unit 2 out of 75, and Units 3, 4 and 5 out of 100 each, as the first table shows. The specification sets Unit 5 as a programmed solution to a problem, assessed in school.
| Unit | A | B | C | D | E |
|---|---|---|---|---|---|
| Computer Science AS Unit 1 | 100 | 88 | 75 | 63 | 50 |
| Computer Science AS Unit 2 | 60 | 53 | 45 | 38 | 30 |
| Computer Science A2 Unit 3 | 80 | 70 | 60 | 50 | 40 |
| Computer Science A2 Unit 4 | 80 | 70 | 60 | 50 | 40 |
| Computer Science A2 Unit 5 | 80 | 70 | 60 | 50 | 40 |
Raw marks per unit, 2025
These are the 2025 figures from the grade converter, with the 2026 change in the last column.
| Unit | A, 2025 | B | C | D | E | A, change on 2026 |
|---|---|---|---|---|---|---|
| AS Unit 1 | 57 | 48 | 39 | 31 | 23 | −6 |
| AS Unit 2 | 41 | 35 | 29 | 23 | 17 | −6 |
| A2 Unit 3 | 54 | 45 | 36 | 27 | 18 | −5 |
| A2 Unit 4 | 54 | 45 | 36 | 27 | 19 | −4 |
| A2 Unit 5 | 70 | 60 | 50 | 40 | 30 | 0 |
Adding a candidate up
With raw marks of 55, 40, 52, 52 and 62, a candidate converts to 97, 59, 78, 78, 72, which is 384 uniform marks. That is a B, 16 marks short of A at 400. The A2 units give 228, against 270 for an A*.
Raw marks and weights
Unit 2 has the lowest uniform maximum, 75, so a mark there is worth more than in Unit 1: an A takes 41 raw marks for 60 uniform marks, while Unit 1 asks for 57 raw marks for 100. That is why you cannot compare raw boundaries between units.
Senedd Research reports 10.5% of Welsh A level entries at A* in 2025 and 97.5% at A* to E.
Unit 5 is unusual because it is assessed in school, so its raw boundary is for a programmed solution and not a timed paper. An A at 70 raw marks and an E at 30 span 40 marks, the same in 2026. Treat it as a coursework unit where planning and testing earn marks over weeks, not hours.
Reading the 2025 table
- The programmed solution was the highest. An A needed 70 raw marks.
- Units 3 and 4 matched. Both needed 54 for an A.
- An E needed different amounts. It was 23 in Unit 1, 17 in Unit 2 and 30 in Unit 5.
