How to use this

This ranks chapters by marks — but it isn’t a study order. A high-weightage chapter often sits on top of two or three others, so working strictly top-down backfires. The reliable path is prerequisite order: build the chapters that unlock the rest, then bank the high-weightage ones once you’re ready for them.

See the Math study plan in prerequisite order →

Weightage tells you where the marks are — not the order to learn them. Rhovecs sequences the chapters by what unlocks what, picks each next question, and schedules revision so the high-yield chapters actually stick.
