GCSE topic heatmaps
Each cell counts how many past-paper citations appear in the original heatmap Word documents for that topic and exam sitting (June or November, aggregated across papers 1–3). Darker red means more citations in that sitting.

Counts follow the citations embedded in those documents (how often each subtopic was examined). MathsVault digitises and re-aggregates; it does not replace exam-board specifications. Generated 2026-04-19T14:13:36Z (UTC).
Sitting keys use ISO months: 2019-06 is the June 2019 series; 2019-11 is November 2019. Topic rows sometimes combine consecutive codes from the Word layout (joined with ·).
