Enter your total mark and see the grade it actually earned in June 2026 — using the published AQA, Pearson Edexcel or OCR boundary table. Then see exactly how many marks separated you from the next grade.
Choose your board and tier, enter your total mark, then calculate. We'll show the grade that mark earned in June 2026 and the next published boundary.
There is no universal GCSE percentage that always equals a grade 4, 5, 7 or 9. Boundaries are specific to the exam board, qualification, tier and exam series. This calculator therefore uses the published June 2026 qualification totals for AQA 8300, Pearson Edexcel 1MA1 and OCR J560 rather than inventing a generic conversion.
That also means the result is deliberately labelled a June 2026 equivalent. It is useful for understanding a real result or benchmarking a past paper against that series, but it cannot predict the boundary for a future paper.

No. It is a lookup of the published June 2026 GCSE Maths qualification boundaries. It tells you what a total mark would have earned in that exam series. Future grade boundaries can move.
AQA GCSE Mathematics 8300, Pearson Edexcel GCSE Mathematics 1MA1 and OCR GCSE Mathematics J560, for both Foundation and Higher tiers.
Enter the total raw mark across all papers in the qualification. AQA and Edexcel Maths are out of 240 marks in the June 2026 boundary tables; OCR Maths is out of 300.
Foundation tier awards grades up to 5. Students aiming for grades 6 to 9 need Higher tier. The calculator only shows grades available on the selected tier.
Use the raw total mark if you have it. Percentages can hide an important detail: the official boundaries are published as marks for an exact board, specification, tier and exam series, not as one universal GCSE percentage.
If the calculator shows the next grade is within reach, Lightbulb helps you work topic by topic rather than staring at the whole Maths course.
