GCSE Maths Grade Boundaries

Grade boundaries are the minimum marks needed to reach each grade in a GCSE Maths exam. Each exam board (AQA, Edexcel and OCR) sets its own boundaries after every session to reflect how hard that paper was, so the mark needed for a grade 9 changes each year and differs between boards. Use the table and calculator below to see how marks map to grades and how close you are to the next grade up.

GCSE maths grade boundaries are the minimum number of marks needed for each grade from 1 to 9. Each exam board (AQA, Edexcel and OCR) sets its own boundaries after every exam series, and they shift slightly each year depending on how hard the papers were. Use the tool below to check the exact marks for your board, tier and year, or read the full tables further down.

What grade boundaries mean in GCSE maths

Grade boundaries are the minimum marks you need to achieve each grade. Examiners set them after every exam series once papers are marked, based on how difficult the papers were and how students performed overall. This keeps a grade meaning the same standard from year to year, even when one year's paper is harder than another's. To see how those papers and marks are split across the exam, read our guide to the GCSE maths exam structure. Boundaries apply across the whole syllabus, so it helps to know the full list of GCSE maths topics you will be assessed on.

How many marks do you need for each grade in GCSE maths?

The exact mark for each grade changes by exam board, tier and year. The figures below are from the most recent series we hold. Use the tool above for any board, tier or year. If you are aiming higher, our guide to the hardest GCSE maths topics shows where the marks are won and lost.

Foundation tier vs Higher tier grade boundaries

GCSE maths has two tiers. Foundation tier covers grades 1 to 5, and Higher tier covers grades 4 to 9. Because the papers are different, the same grade needs a different number of marks on each tier. A grade 4 on Foundation usually needs more marks than a grade 4 on Higher, since the Higher paper is harder.

Why do GCSE maths grade boundaries change every year?

Boundaries are set after each exam series, not before. If a paper turns out harder than usual, the boundaries are lowered so students are not penalised for a tougher paper, and if it is easier they rise. This is why last year's marks are only a guide, and why you should never assume this year's boundaries will match.

When are GCSE maths grade boundaries released?

Each exam board publishes its final grade boundaries on GCSE results day in August, on the morning results are released. Provisional boundaries are not usually shared before then. This page is updated with each new series once the official figures are out.
