Maths Optional — Study Guide
One chapter per syllabus topic: the recurring question patterns, the minimum theory that cracks them, and verified worked examples from thirteen years of papers. We're publishing chapters in exam-priority order — sphere is the flagship sample.
188 chapters live · publishing in exam-priority order.
Every chapter is tagged by how often its topic is tested:
- Core
- Tested most often — the exam’s bankable core.
- Reliable
- Comes up frequently — a dependable scorer once you know it.
- Occasional
- Shows up sometimes, not every year.
- Rare
- Long tail — appears rarely, sometimes only once in 13 years.
