In June 2026, a grade A in AQA A-level Biology needed 174 out of 260 raw marks — 67%. An A* needed 199 (77%). That's 9 marks higher than June 2025 — the paper was found easier, so more marks were needed.

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.
199 out of 260 in June 2026 — 77% of the raw marks.
67% in June 2026: 174 raw marks out of 260. The percentage moves each year with the paper's difficulty — the grade is fixed, the marks aren't.
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.
