How to use these grade boundaries
- Sit the June 2025 paper timed, then mark it strictly with the mark scheme.
- Check your raw mark against the boundaries for that component above to see roughly where you are.
- Read the examiners' report for every question where you dropped marks.
Boundaries move from year to year as papers get harder or easier. See how they compare across every year.
