Cambridge — the only board publishing this subject
Board by board · 2025
With a single board there is no cross-board comparison to draw; the figures below are the complete published picture.
Grade distributions reflect who enters a subject as much as the exam itself, so nothing on this page is a difficulty ranking. Figures are published cumulative percentages from JCQ and the awarding bodies; per-grade shares are derived by subtracting adjacent bands. How the data is sourced and worked out.
