How do I work out my Cambridge grade from raw marks?

Find your raw mark, the paper or aggregate total, and the grade thresholds for your session. Enter them above and the calculator returns your grade, your percentage, and how many marks you are from the next grade up. Boundaries are raw marks, not fixed percentages.

Where do I find the official grade boundaries?

Cambridge publishes a grade threshold table for every syllabus and session on results day, on the Cambridge International website under Grade threshold tables. Your school exams officer also receives them. June 2026 thresholds are released on 13 August 2026.

Are these the real 2026 grade boundaries?

No — you enter the boundaries yourself, so the result is always based on real, official numbers rather than a guess. The 2026 thresholds are not published until results day, so before then you can estimate using the most recent two or three sessions for your components.

Why does the boundary for an A change every year?

Cambridge sets boundaries after marking so a grade means the same standard each year. If a paper is harder than usual the boundary drops; if easier it rises. That is why an A might need 65% one session and 72% another — always check the table for your session.

Enter your mark, the total, and at least one boundary to see your grade.

How Cambridge grade boundaries work

After every script is marked, Cambridge sets the boundary for each grade so that the standard stays consistent year on year. If a paper is harder than usual, the boundary is lowered; if easier, it is raised. That is why you cannot rely on “80% is always an A”. For a full A-Level, your grade is based on a weighted total across your components, and the A* additionally requires a strong A2 performance.
