Why do Biology grade boundaries change every year?

Because they're set after the papers are marked, once examiners can see how hard students found that year's exam. If a paper was harder, the boundary drops so the same standard of work still earns the same grade. That's why a boundary from a previous year is never a safe prediction for this year.

Are these the marks for the whole subject or for one paper?

The whole subject. AQA also publishes "notional" per-paper boundaries, but those are illustrative only — your grade is decided by your total subject mark against these subject-level boundaries, so those are the numbers we show.

What's the difference between Higher and Foundation boundaries for Biology?

Higher tier targets grades 9–4 (with grade 3 as a narrow safety net); Foundation targets grades 5–1. They're different papers, so the raw-mark boundaries aren't comparable across tiers — use the table for the tier you're entered for.

What mark do I need to pass Biology?

A grade 4 is the "standard pass" and a grade 5 is a "strong pass". The exact raw mark for a 4 changes each year — see the grade 4 row above for the most recent figures, but treat them as a guide, not a fixed target.

The raw marks needed for each grade in AQA GCSE Biology (8461), straight from AQA'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.

Tiered: Higher tier targets grades 9–4 (grade 3 is a narrow safety-net grade); Foundation tier targets grades 5–1.

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 →
