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.
