Cambridge grade boundary calculator

Turn raw marks into a Cambridge grade. Enter your mark, the total, and the official thresholds for your session — get your A*–E grade, your percentage, and exactly how many marks you need for the next grade.

Enter the boundary marks from your official Cambridge grade threshold table for the exact session. Leave a grade blank if you don’t have it.

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. Read the full method in our guide to reading grade boundaries.
