GCSE Maths Percentage to Grade Calculator (9-1)
This converter maps your GCSE Maths percentage to a 9-1 grade using official Pearson Edexcel 1MA1 boundaries from June 2025 and November 2025. Recent reality check: grade 9 on Higher has needed about 88-90%, while a grade 4 standard pass on Higher has needed only about 21-22% — and Foundation's ceiling is grade 5. Boundaries reset every session, so results show the two-session range, not one false-precision number.

Boundary ranges (Jun + Nov 2025)
- Grade 987.9% – 90.4%
- Grade 875.8% – 77.5%
- Grade 763.7% – 65.0%
- Grade 649.6% – 50.4%
- Grade 535.4% – 36.3%
- Grade 421.3% – 22.1%
- Grade 314.2% – 15.0%
How the conversion works
Formula: boundary mark ÷ 240 × 100 = boundary percentage (1MA1 total is 240 raw marks across three papers on either tier). Your percentage is compared against both recent sessions' boundary percentages for your tier.
Worked example
You scored 64% on Higher tier — that is 153.6/240 raw. Grade 7 needed 156/240 (65%) in June 2025 but 153/240 (63.75%) in November 2025: you are inside the grade-7 borderline zone — secure grade 6, possible 7. The tool flags exactly this: revise to clear 65% and the 7 is safe in either session's terms.

GCSE Percentage to Grade — FAQ
How GCSE 9-1 percentages map to grades.
What percentage is a grade 9 in GCSE Maths?
On Edexcel 1MA1 Higher tier, the grade 9 boundary was 217/240 = 90.4% in June 2025 and 211/240 = 87.9% in November 2025. Roughly 88-90% of the raw marks has been the recent grade-9 zone — but it is reset every session, so treat any single figure as a guide.
What percentage is a grade 4 (standard pass) in GCSE Maths?
Much lower than most students expect. On Higher tier, grade 4 needed 53/240 = 22.1% in June 2025 and 51/240 = 21.3% in November 2025. On Foundation, grade 4 needed 144/240 = 60% in June 2025. The same grade sits at very different percentages on each tier — always select your tier in the calculator.
What grades can I get on Foundation vs Higher tier?
Foundation awards grades 5 to 1 — grade 5 is its ceiling. Higher awards 9 to 4, with grade 3 available as a safety-net "allowed grade" just below the grade-4 boundary; below that the result is Unclassified. If you are targeting grade 6 or above you must sit Higher.
Are these boundaries the same for AQA and OCR GCSE Maths?
No. Each board sets its own boundaries per session, and they differ by a few marks. This calculator uses Pearson Edexcel 1MA1 — the most-sat GCSE Maths specification and the one most Dubai British-curriculum schools using domestic GCSE enter. AQA and OCR patterns are similar but not identical.
How reliable is a percentage-based GCSE grade prediction?
It is a planning tool. The boundaries here are official published values from the two most recent sessions, and the calculator shows where your score falls against BOTH — if you are inside the range between them, you are borderline and should treat the higher session as your revision target. Boundaries for your actual session will differ slightly.
