How the IGCSE grade calculator works
Each exam series, Cambridge and Edexcel publish the minimum total mark needed for every grade. This tool maps your mark to the matching grade for the session you choose. Boundaries shift slightly each series, so always pick the right session — and treat estimates from past series as a guide, not a guarantee.
Frequently asked questions
Are these the official grade boundaries?
Figures come from each board's published grade threshold tables. This is an independent study tool — always confirm against your exam board's official release.
What grade is a pass in IGCSE?
A grade 4 (formerly C) is widely treated as a standard pass, and a grade 5 as a strong pass — but requirements depend on your school, college or university.
