Paper Comparison

December 2024 against December 2025

What one sitting asked that the other did not — as a share of each paper, because December 2024 carries 200 subject questions and December 2025 carries 98. Comparing raw counts across papers of different sizes invents a trend in every row.

Present on one paper and absent from the other

Absent from one sitting is not absent from the syllabus. A topic carrying two questions one session and none the next has told you almost nothing.

25 of 31 topics moved by less than 1.5 percentage points and are greyed out — at four to thirteen questions a topic, a swing of one or two questions is noise, not a signal.

Two sittings are two sittings. Everything above describes what these two papers contained. None of it predicts the next one, and a topic that fell here is not a topic to drop — the examiners are not running a trend. The aggregate across every complete paper is the more reliable number, and it is still only four papers.
