Why I built IB Math Revision

After more than a decade teaching IB Maths — through the pre-2019 syllabus (Math Studies, Math SL, Math HL) and into the current four courses (SL AI, SL AA, HL AI, HL AA) — I got fed up watching capable students lose 5–10 marks in the final exam not because they didn't understand the maths, but because they'd never practised it under proper conditions with proper feedback. The best textbooks stop at the end of each chapter; the best tutors cost more than most families can sustain across two years of DP.

So I built the site I wish existed when I was Head of Maths: every SL and HL syllabus unit worked through in AI-graded questions that give method-mark feedback (not just a right/wrong tick), mark-scheme walkthroughs that actually explain the M / A / R marks, printable PDF workbooks, a Path-to-7 progress ladder, and — for students who need it — a €5 AI IA feedback tool plus a €100 human examiner review with a 20-minute meeting.

Every question, mark scheme and blog article on this site is written or vetted by me. No content mills. No filler.
