9 is the top, 1 is the bottom
England’s reformed GCSEs use numbers, not A*–G. Grade 9 is the highest, then 8, 7, and so on down to 1. U (unclassified) sits below 1. A 9 is harder to earn than the old A*; most high A* work maps nearer to 8 or 9 depending on the paper.
What counts as a pass
Grade 4 is a standard pass. Grade 5 is often called a strong pass. Many sixth forms and employers ask for grade 4 or 5 in English and maths. That is not the same as a US D or C — do not convert it on a US A–F table.
Percentage bands are not official
Exam boards set new grade boundaries every series and every subject. A 70% might be a 7 on one paper and a 6 on another. Our GCSE calculator uses a simplified educational map so you can plan. It is not Ofqual, AQA, Edexcel, OCR, or WJEC.
How to use the GCSE calculator
Enter a percentage from 0–100. Read the 9–1 grade, whether it is a standard pass (4+), the percentage band we used, and an approximate legacy A*–G letter. Change the number to see what it would take to move up a grade.
Legacy A*–G letters
Older certificates and some international GCSEs still show letters. Roughly, 7–9 sit near A/A*, 4 is around a C, and 1 is a G. Use that only as a memory aid. If your school still reports letters, use the letter-grade tools on the matching scale instead.
GCSEs are not a UK degree class
A First at university is typically 70%+ on a degree classification. A GCSE 7 is also often near 70% on our educational table, but they are different qualifications. After you have A-level or university marks, switch to the UK degree classification calculator.
Scotland, Wales, and Northern Ireland
This guide is about the England 9–1 scale. Scotland uses National 5 / Higher. Wales and Northern Ireland may still mix letters and numbers depending on the board. Check your exam board’s page before you treat a number as official.
