Study hours calculator for your exam

Last updated 8 November 2026.

Enter your exam date, the hours you can study each day and your subjects. The calculator shows how many study days and hours you have left, keeps time for final revision and splits the rest across your subjects by difficulty.

What you get

• Days and hours left. Counts study days to your exam after rest days.
