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. Verified absent: Pearson's grade-boundaries page June 2026 document list contains only BTEC Nationals, T Levels, AEA, GCE A-level (subject and notional component), International A-level, Edexcel Awards L3, Core Maths and Level 3 Project. 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.

|---|---|---|
| 5 | 130 | 65% |
| 4 | 111 | 56% |
| 3 | 81 | 40% |

| 5 → 4 | 19 marks |
| 4 → 3 | 30 marks |
| 3 → 2 | 30 marks |
| 2 → 1 | 29 marks |
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.
130 out of 200 in June 2025 — 65% of the raw marks.
56% in June 2025: 111 raw marks out of 200. 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.
