Pearson Edexcel GCSE Combined Science grade boundaries

Data source: Pearson Edexcel GCSE (9-1) grade boundaries (June 2025) · 2024–2025 data · checked July 2026How we verify →

The raw marks needed for each grade in Pearson Edexcel GCSE Combined Science (1SC0), straight from Pearson Edexcel's official tables. Boundaries are set after every paper is marked, so a lower boundary usually means the paper was harder that year — not that the grade got easier. That's why we show more than one year.

Double award — worth two GCSEs, graded on a paired scale (9-9 … 1-1). Max 360 marks across all six papers.

Reform watch:England's 2025 Curriculum & Assessment Review doesn't change GCSE or A-level content until reformed specs are first taught (national curriculum September 2028; updated GCSEs from 2029). Your 2026–2028 exams use the current specification. What's changing →

How to read these. A boundary is the minimum raw mark for that grade — score it or above and you get the grade. They're a whole-subject total, not a per-paper pass mark, and they change every year. Never treat a past year's boundary as this year's target. Why GCSE grade boundaries move →
