A GCSE grade comes from raw marks, not a fixed percentage. Each exam board sets its grade boundaries after marking, so they change every series and differ by paper and tier. In AQA's June 2026 maths, published on 20 August 2026, Higher tier needed 63 of 240 marks (26%) for grade 4 and 97 (40%) for grade 5, while Foundation tier needed 154 (64%) for grade 4 and 187 (78%) for grade 5. Foundation awards grades 5 to 1 and Higher grades 9 to 4, with a grade 3 for a narrow miss (Ofqual, 2026). The calculator below is a rough estimate from approximate percentages, not a board boundary.

The percentages in this table are fixed, approximate figures used for the estimate. They are not taken from any one board's published boundaries. The exam boards (AQA, Pearson Edexcel, OCR and WJEC Eduqas) set the real ones after marking each series and publish them on results day, so use those for any decision.
