The 2026 lines for Computer Science (1CP2)
These come from Pearson's June 2026 GCSE (9-1) document. The table sets them beside 2025 and 2024.
| Grade | 2024 | 2025 | 2026 | 2026 on 2025 | 2026 share of 150 |
|---|---|---|---|---|---|
| 9 | 119 | 124 | 118 | −6 | 79% |
| 8 | 105 | 109 | 103 | −6 | 69% |
| 7 | 91 | 94 | 88 | −6 | 59% |
| 6 | 76 | 79 | 74 | −5 | 49% |
| 5 | 61 | 64 | 60 | −4 | 40% |
| 4 | 47 | 49 | 46 | −3 | 31% |
| 3 | 34 | 36 | 33 | −3 | 22% |
| 2 | 21 | 23 | 20 | −3 | 13% |
| 1 | 8 | 10 | 8 | −2 | 5% |

Back to the 2024 level
After a rise in 2025 the lines came back. Grade 9 fell from 124 to 118, which is one mark below the 119 of 2024. Grade 7 fell from 94 to 88, and grade 4 from 49 to 46, 1 below 2024. Grade 1 returned to 8, the same as in 2024.
Ofqual explains that grade boundaries often vary from year to year to reflect the difficulty of each paper, so a fall like this reflects the papers and not a change to the standard.
Where the 150 marks come from
| Paper | Format | Length | Marks |
|---|---|---|---|
| Paper 1: Principles of Computer Science (1CP2/01) | Written | 1 hour 30 minutes | 75 |
| Paper 2: Application of Computational Thinking (1CP2/02) | On screen, Python 3 | 2 hours | 75 |
There are no tiers. A student who is strong on the screen paper can make up marks lost on the written one, because the boundary is only for the total.
A 2026 worked example
A student scores 38 on Paper 1 and 29 on Paper 2, a total of 67. The 2026 lines are 5 at 60 and 6 at 74, so 67 is a grade 5, 7 marks short of a 6. In 2025 the same total would have been a grade 5 as well, but 12 marks short of a 6, because the 2025 grade 6 line was 79.
Planning. Grade 4 is 31% this year. Spend practice time on Paper 2 questions where you write code, since those marks are hard to earn without running a program.
How far apart the grades are
In 2026 the step from grade 4 to grade 5 was 14 marks and from grade 5 to grade 6 it was 14. From grade 6 to 7 it was 14, and the steps from 7 up to 9 were 15 and 15. Marks per grade are smaller at the bottom: grade 1 to grade 2 is 12 and grade 2 to grade 3 is 13.
If you sit just under a line, the gap above you is the number that matters. On 83 you are 9 above the grade 6 line of 74 and 5 below the grade 7 line of 88, so one solid extended answer separates the two.
