How this paper is actually marked
A deeper layer on top of the lessons: a guide to every question type this paper sets, every topic, term and formula it examines, practice with keys, and what has actually been asked. Every claim traces back to a real mark scheme, examiner report or spec document — genuine gaps are flagged, never papered over.
Topics
One guide per topic: the idea, worked examples, and every real question that has tested it.
