IB revision notes: Maths AA, Maths AI and Physics, PDF

Each chapter covers a group of syllabus points and follows the same shape, so that after the first one you know where to look: what the topic is and what the exam asks of it, the definitions and key results, the formulas marked "in the booklet" or "learn it", three original worked examples solved step by step, the common errors, and a checklist.

The last page of every chapter is the chapter in one page: what to know by heart, how to attack the typical question, the traps. It is the page to print, photograph and pass around in the week before the exam.

Notes that are sold get copied anyway. Notes without a price get shared on purpose, and the copy that goes around is the current one, with the version number and the address where the corrections live.

The notes are the written form of what happens in lessons. If you want a second opinion on where you stand before the exam, a 20-minute assessment session carries no charge.

Every chapter is written from the syllabus, then every statement and every worked example is checked blind by a second reader who does not see the solutions, then read again by the author. Written with the help of AI tools and checked by hand.

No system is perfect, which is why every volume carries a version number. A mistake reported today is fixed in the next version, and the course page says what changed.
