Grade boundaries are the minimum raw marks needed to achieve each grade in a GCSE exam. They are set by exam boards after all papers have been marked, using a process called "comparable outcomes".
This ensures that roughly the same proportion of students achieve each grade from year to year, even if one year's exam was harder or easier than another's. The boundaries are different for every subject, exam board, tier, and year.
Our calculator compiles official boundary data from all major UK exam boards - AQA, Edexcel, OCR, and WJEC/Eduqas - covering over 30 subjects across 4 years (2022-2025).
