121 / 200 raw marks for a grade 4 · June 2025 · 60%

June 2026 is not out yet. NOT PUBLISHED YET. GCSE results day 2026 is Thursday 20 August 2026; 13 August 2026 was A-level results day, so the premise that GCSE results day was last Thursday is incorrect. AQA releases GCSE boundaries at 08:00 on 20 Aug 2026. Verified absent: AQA's grade-boundaries page and archive list June 2026 files only for A-level, AS, L3 Certificate in Mathematical Studies, Applied General and EPQ. max_mark is the specification total, not a 2026 observation. Everything below is the most recent series the board has actually published — no figure on this page is a prediction.

The gap table is the revision-planning number: it's how many extra marks each grade actually costs. A gap this size is usually one exam question done properly, not a different student.

Questions

How many marks do you need for a 5 in AQA Biology (Foundation tier)?

140 out of 200 in June 2025 — 70% of the raw marks.

What percentage is a 4 in AQA GCSE Biology (Foundation tier)?

60% in June 2025: 121 raw marks out of 200. The percentage moves each year with the paper's difficulty — the grade is fixed, the marks aren't.

Why do grade boundaries change every year?

Boundaries are set after marking so that a grade represents the same standard despite papers varying in difficulty. A harder paper gets lower boundaries; an easier one gets higher. Predicting next year's boundary from this year's is guessing the difficulty of an unwritten paper.
