Eduqas GCSE Computer Science grade boundaries June 2025
Computer Science (entry code C500QS) has no tiers, so every student can reach every grade from 9 to 1. The figures are copied from Eduqas GCSE Grade Points, June 2025, last updated on 20 August 2025.
| Grade | Lowest total mark (out of 200) | Share of the total |
|---|---|---|
| 9 | 161 | 81% |
| 8 | 148 | 74% |
| 7 | 135 | 68% |
| 6 | 115 | 58% |
| 5 | 95 | 48% |
| 4 | 76 | 38% |
| 3 | 54 | 27% |
| 2 | 32 | 16% |
| 1 | 10 | 5% |
The board-wide table, which also covers Maths and all other subjects, is at Eduqas GCSE grade boundaries 2025.
Two components, and why the programming paper is scaled
Eduqas's specification sets two components and no coursework. Component 1, Understanding Computer Science, is a written exam of 1 hour 45 minutes worth 100 marks and 50% of the qualification. Component 2 is an on-screen exam of 2 hours, worth 80 marks and 50%, and it uses Python 3. Because 80 marks has to count the same as 100, the grade points file gives Component 2 a weighting factor of 1.25. The file calls this component Computational Thinking and Programming.
The notional component boundaries for June 2025 are below. Eduqas describes them as a guide for centres, not official grades.
| Grade | Component 1 (out of 100) | Component 2 (out of 80) | Overall (out of 200) |
|---|---|---|---|
| 9 | 73 | 70 | 161 |
| 8 | 64 | 67 | 148 |
| 7 | 55 | 64 | 135 |
| 6 | 46 | 55 | 115 |
| 5 | 36 | 47 | 95 |
| 4 | 27 | 39 | 76 |
| 3 | 20 | 27 | 54 |
| 2 | 13 | 15 | 32 |
| 1 | 6 | 3 | 10 |
Add the two columns, scaling Component 2 by 1.25, and you get the overall column to the nearest mark: a grade 7 is 55 + 64 × 1.25 = 135, and the overall boundary is 135.
A worked example with the scaling
A student scores 48 on Component 1 and 44 on Component 2. Scale the second paper first: 44 × 1.25 = 55. The total is 48 + 55 = 103 out of 200. In the table, 103 is above 95 (grade 5) and below 115 (grade 6), so the grade is a 5, 12 marks short of a 6. Every extra mark on the programming paper is worth 1.25 on the total, so it pays to practise your Python.
A grade 4 is different on the two papers
On the overall table a grade 4 is 38% of the marks. The component figures show where those marks come from: 27 out of 100 on the written paper but 39 out of 80 on the programming paper, which is 49%. At a grade 4 the programming paper asks for a much bigger share of its marks than the written paper does. Our GCSE Computer Science guide covers what each paper tests.
2025 compared with 2024
The June 2024 file shows how the year changed. The change column is 2025 minus 2024.
| Grade | 2024 | 2025 | Change |
|---|---|---|---|
| 9 | 160 | 161 | +1 |
| 8 | 150 | 148 | −2 |
| 7 | 140 | 135 | −5 |
| 6 | 118 | 115 | −3 |
| 5 | 96 | 95 | −1 |
| 4 | 75 | 76 | +1 |
| 3 | 53 | 54 | +1 |
| 2 | 31 | 32 | +1 |
| 1 | 10 | 10 | 0 |
Grade 7 fell from 140 to 135 and grade 8 from 150 to 148, which means a student needed fewer marks for a 7 than the year before. Grades 9, 4, 3 and 2 each rose by 1 mark. The pass mark for the lowest grade, a 1, stayed at 10.
Using the boundaries
- Revise both papers. Each one is half the qualification, so neither can be neglected.
- Aim for a share, not a mark. A grade 4 was 38% and a grade 7 was 68% in 2025.
- Expect movement. Eduqas sets boundaries after the papers are marked, so next year will differ.
Today's paper
GCSE Computer Science has a new 8-question paper every day on our practice papers, worth 25 to 35 marks and not written by Eduqas. Mark it and turn your score into a percentage, then compare with the share column above. A result of 25 out of 30 is 83%, above the 81% a grade 9 needed in this table, though one short paper proves little. For a fuller picture look at how to predict a GCSE grade from several.
