⚠️ Real GCSE grade boundaries are set per subject, per exam board, per year (AQA, Edexcel, OCR, WJEC) and are often much lower than these illustrative marks — maths grade 4 has been near 20% on higher tier. Use the official boundaries from your board for anything that matters; this table is for orientation and old-vs-new comparison.
🇬🇧GCSE grades 9–1, finally clear
England swapped A*–G letters for numbers 9–1— with 9 above the old A*, and two different “passes” that confuse everyone. This tool puts the full 9–1 ↔ A*–G conversion table in one place, explains standard vs strong passes, and estimates a grade from a mark using clearly-labelled illustrative boundaries.
🎯The two passes explained
- Grade 4 = 'standard pass' (old C) — the minimum most colleges, apprenticeships & jobs require; below 4 in English/maths usually means resits.
- Grade 5 = 'strong pass' (high C/low B) — the benchmark school league tables use, and what competitive sixth forms often ask for.
- Grade 7 ≈ old A, grade 8 sits between A and A*, and grade 9 is HARDER than A* — only about the top 4–5% of results.
- Grades 9–7 are the 'top grades' universities notice on applications years later.
⚠️About grade boundaries
Real boundaries are set per subject, per exam board (AQA, Edexcel, OCR, WJEC), per year — after marking, to keep standards stable. They can be dramatically lower than intuition suggests: maths higher-tier grade 4 has fallen near 20% in some years. The estimator here uses illustrative bands for orientation; for results day, only your board's published boundaries count.
💡 Frequently Asked Questions
What is a grade 4 in GCSE?+
A 'standard pass', equivalent to the bottom of the old grade C. It satisfies most college and job requirements. Grade 5 is the 'strong pass' (high C to low B) that league tables measure and competitive sixth forms often demand.
What is grade 9 equivalent to in old GCSE letters?+
Above the old A*. Grades 8 and 9 together span A*, with 9 reserved for roughly the top 4–5% of entries — it was deliberately designed to distinguish the very best among A* students.
What percentage is each GCSE grade?+
There is no fixed answer — boundaries are set per subject, board, and year after marking. As orientation: grade 4 often falls anywhere from 20–50% depending on tier and subject, while grade 9 typically needs 75–90%. Always check your exam board's published boundaries.
Do GCSE grades 9–1 apply in Scotland or internationally?+
Scotland uses its own National 5 system, and Wales kept A*–G. International GCSEs (iGCSE) have largely moved to 9–1 too. If you're comparing internationally, grades 9–7 map to A*/A, 6–5 to B, and 4 to C.
