WJEC A-level Computer Science grade boundaries June 2026
Computer Science (1500) has five units, per the specification: Fundamentals of Computer Science (Unit 1), Practical Programming to Solve Problems (Unit 2), Programming and System Development (Unit 3), Computer Architecture, Data, Communication and Applications (Unit 4) and a programmed solution to a problem (Unit 5). Their uniform marks are 125, 75, 100, 100 and 100, a different split from the sciences, and the first table gives the unit grades.
| 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, 2026
The raw marks come from WJEC's grade converter for June 2026.
| Unit | A, 2026 | B | C | D | E | A, change on 2025 |
|---|---|---|---|---|---|---|
| AS Unit 1 | 63 | 54 | 45 | 37 | 29 | +6 |
| AS Unit 2 | 47 | 41 | 35 | 29 | 24 | +6 |
| A2 Unit 3 | 59 | 49 | 40 | 31 | 22 | +5 |
| A2 Unit 4 | 58 | 49 | 40 | 31 | 23 | +4 |
| A2 Unit 5 | 70 | 60 | 50 | 40 | 30 | 0 |
A worked total
A candidate scores 58, 45, 55, 55 and 65 raw marks in Units 1 to 5. The converter gives 93, 58, 76, 77, 75, a total of 379 out of 500. That is above the B boundary of 350 and 21 short of A at 400. The A2 units supply 228, so an A* would need 270 there.
Four units up, one unchanged
The raw mark for an A rose by 6 in Unit 1, 6 in Unit 2, 5 in Unit 3 and 4 in Unit 4. Unit 5 stayed at 70 for an A and 30 for an E in both years. That is a different pattern to Chemistry or Physics, where the A2 boundaries fell. A raw boundary that rises usually means the paper was easier to score on, so Computer Science candidates needed more of the available marks to show the same standard.
Senedd Research reports that Welsh A level entries in Computing fell by 71 (14.5%) in 2026, the largest fall of any subject.
Using the 2026 table
- The programmed solution is fixed. It is assessed in school, and an A needed 70 raw marks in both years.
- Unit 2 is a shorter unit with big swings. Its E went from 17 to 24, a rise of 7.
- Unit 1 carries 25% of the A level. It is worth 125 uniform marks, the most of any unit.
