Edexcel GCSE Computer Science (1CP2) boundaries, 2025
From Pearson's June 2025 GCSE (9-1) document, with June 2024 from its 2024 document.
| Grade | 2024 | 2025 | Change | 2025 as a share of 150 |
|---|---|---|---|---|

| 8 | 105 | 109 | +4 | 73% |
| 7 | 91 | 94 | +3 | 63% |

| 1 | 8 | 10 | +2 | 7% |
One tier, two papers
Computer Science has no Foundation and Higher split, so one set of lines covers everyone, from grade 9 to grade 1.
| 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 |
The written paper tests theory and the on-screen paper tests programming, which is why a candidate strong at code and weaker at theory can balance the two. Pearson provides the Programming Language Subset for Paper 2: see our subset guide and the Edexcel GCSE Computer Science guide.
Changes from 2024
Every line rose in 2025. Grade 9 went from 119 to 124, up 5, and grade 7 from 91 to 94, up 3. Grade 4 rose 2, from 47 to 49, among the smallest rises, and grade 1 rose 2. A student aiming at grade 7 with the 2024 figure would have been 3 marks short in 2025. Pearson's two-paper structure means that gap is shared across a written paper and a programming paper, so it can be closed on either.
A worked example
A student scores 41 on Paper 1 and 38 on Paper 2. The total is 79 out of 150, which is exactly the grade 6 line of 79, so it is a grade 6. One mark fewer, 78, would have been a grade 5, and a grade 7 needs 15 more.
A boundary is the lowest mark for its grade, so landing on it counts in your favour.
How far apart the grades are
Between grade 4 and grade 7 in 2025 there were 45 marks, about 15 marks per grade. The steps are 15 from 9 to 8, 15 from 8 to 7, 15 from 7 to 6, 15 from 6 to 5 and 15 from 5 to 4. So the top grades are packed in tighter than the middle: lifting a grade 5 to a 6 takes 15 marks, while lifting an 8 to a 9 takes 15.
Spread across two papers of 75 marks, a gap of 15 is about 7 or 8 marks on each, the size of one good extended answer.
What it means for revision
- Grade 4 is 33%. Grade 7 is 63% and grade 9 is 83%.
- Paper 2 is practical. The only way to earn the programming marks is to write and test code.
- Paper 1 covers computational thinking, data, computers, networks and issues and impact.
Today's GCSE Computer Science paper is 8 questions and 25 to 35 marks, not an Edexcel paper. Turn the mark into a share and compare it with the table.
