How GCSE grading works
GCSEs are graded 9 to 1, with 9 the highest and 1 the lowest. The 9–1 scale replaced the old A*–G system: grade 9 is reserved for the very top performers and is harder to achieve than the old A*. Grade 4 is a standard pass (roughly the old C) andgrade 5 is a strong pass. English and Maths GCSEs require at least a 4 — or a 5 for many college courses — to progress.
Boundaries are set after each exam series and published by the exam boards, so they shift slightly year to year. If you're waiting for results, the official boundary tables come out on results day — this calculator gives you a realistic estimate beforehand.
Frequently asked questions
What is a pass in GCSE?+
Grade 4 is a standard pass and grade 5 is a strong pass in the current 9–1 system. A grade 4 is roughly equivalent to a C in the old A*–G scale, and grade 5 is a high C / low B. Most sixth-form and college courses ask for at least a 4 or 5 in English and Maths.
How do GCSE grades work?+
GCSEs are graded from 9 (highest) to 1 (lowest). Grade 9 is above an old A*; grade 4 is a standard pass; grade 1 is the lowest. The old scale maps roughly as: 9 ≈ A**, 8 ≈ A*, 7 ≈ A, 6 ≈ B, 5 ≈ strong C, 4 ≈ C, 3 ≈ D/E, 2 ≈ F, 1 ≈ G.
What percentage is a grade 7 at GCSE?+
Grade boundaries vary by exam board (AQA, Edexcel, OCR, WJEC), subject, and year, but a grade 7 is typically around 65–70% of the total marks. Always check the official boundary tables published by the exam board for your subject.
Do GCSE grade boundaries change every year?+
Yes. Boundaries are set after each exam series based on the difficulty of the paper and how students performed, then published by each exam board. The calculator uses a typical reference table, not official boundaries.
Is a grade 4 a good GCSE grade?+
Grade 4 is a standard pass — it meets the basic requirement for many courses and employers. Grade 5 is a strong pass. For competitive sixth forms, universities, and apprenticeships, 6s and 7s are typically expected in relevant subjects.
How is the 9–1 scale different from A*–G?+
The 9–1 scale was introduced to give more differentiation at the top: grade 9 is harder to get than the old A* and is awarded to the very highest performers. Grades 4 and 5 replace the old C, and grade 1 replaces G. The pass mark moved from C to 4.
