Edexcel GCSE Computer Science (2025) Grade Boundaries

Student-friendly guide for understanding how your Paper 1 + Paper 2 marks combine into a final grade.

How it works (the main thing to remember)

Your final grade is based on your combined total across both papers (out of 150), not a separate grade for each paper.

Example: 32 on Paper 1 + 32 on Paper 2 = 64 total → this reaches the Grade 5 boundary.

Quick target table (Grades 4–6)

Grade Overall boundary
(out of 150)		 Equal split average
(per paper, out of 75)		 2025 notional Paper 01 2025 notional Paper 02
Grade 4 49 24.5 (so think 25 each) 25 24
Grade 5 64 32 each 32 31
Grade 6 79 39.5 (so think 40 each) 40 38

Important: Paper 01 and Paper 02 figures above are notional (a guide). The qualification grade is awarded from the overall total.

Type in your scores (0–75 each) to estimate where your total sits using the 2025 overall boundaries.

Total: 64 / 150
Estimated grade: 5 ✅

This is based on the June 2025 Edexcel GCSE Computer Science overall grade boundaries.

Safer classroom targets (with a cushion)

Grade 4 target: aim for 27+ per paper (about 54 total)
Grade 5 target: aim for 35+ per paper (about 70 total)
Grade 6 target: aim for 41+ per paper (about 82 total)

Why a cushion? Because sitting exactly on the boundary is risky. One silly mistake = pain. We avoid pain.

Frequently asked question

“If I get 32 on both papers, is that a Grade 5?”

Yes. 32 + 32 = 64, and 64 is the Grade 5 boundary for the 2025 Edexcel GCSE Computer Science qualification.

Heads-up: Grade boundaries can change each year, so always check the official boundaries for your exam series.
