Widely called the “holy grail” of IB Maths, this site was created by an Oxford-educated IB Maths teacher with over 20 years of experience. It is recommended by virtually every other IB resource site and is the single most important free resource available.

Everything is free and available as downloadable PDFs: complete lecture notes for all four courses, massive exercise banks organised by sub-topic with full worked solutions, custom formula booklets for each course, dozens of practice tests (in both PDF and editable Word format), HL Paper 3 specimen questions with solutions, and dedicated GDC (graphing calculator) guides.

The main limitation is that there are no videos and no interactive tools — it’s purely PDF-based study material. But the depth and quality of the written content is unmatched. If you use only one resource, make it this one.

Best for: Complete study notes, exercises with full solutions, formula booklets. The foundation of any IB Maths study plan.

The market leader — Revision Village claims that 85% of IB Diploma students use their platform, and reports that Gold subscribers outperform the global IB average by 34%. It is the most polished and feature-rich IB Maths platform available.

Paid subscribers get access to over 40,000 exam-style questions with video solutions, full practice exams (quizzes, revision ladder, mock papers), Prediction Exams released before each IB session based on trend analysis, past paper video walkthroughs, key concept summary videos, the Newton AI tutor for Socratic-style guidance, HL Paper 3 resources, bootcamps, and mobile apps for iOS and Android.

The free tier is limited to Topics 1–2 of the question bank, a community Discord, and mobile app access. There is no IA or coursework support. The main barrier is cost: $249 for a single course or $499 for all four courses.

Best for: Video solutions, prediction exams, and structured exam prep. The best option for students who learn primarily through video and want prediction papers.

RevisionDojo is the strongest all-in-one platform for IB Maths, combining a massive question bank with AI-powered feedback, coursework grading, and a generous free tier. Founded in 2023, it’s newer than Revision Village but has rapidly built a comprehensive feature set.

The platform offers 10,782+ maths questions with AI-powered feedback aligned to IB mark schemes, mock exams with a custom test builder, flashcards with spaced repetition, an AI study partner (“Jojo”) for step-by-step explanations, expert-written notes and textbooks, HL Paper 3 solutions and strategy guides, and — on the Pro tier — predicted papers, IA/EE/TOK coursework grading with AI, 5,000+ graded exemplars, and one-to-one tutoring at $29/hour.

The free tier is genuinely generous: unlimited question bank access, basic AI chat, flashcards, test builder, and exam mode. This makes it the best free all-in-one platform. The main caveat is its shorter track record compared to Revision Village.

Best for: AI-powered practice, coursework grading, and students who want an all-in-one platform. Best value for money across all IB Maths platforms.

Save My Exams provides the most detailed topic-by-topic revision notes available for IB Maths. Written by IB teachers and examiners, the notes are comprehensive, clearly structured, and accompanied by topic questions with model answers, flashcards, and practice papers.

The official site is behind a paywall, but the SME Archive mirrors the content for free. This archive is part of the pirateIB ecosystem and is an unofficial redistribution — use it at your discretion. For students who prefer reading-based revision over video, Save My Exams is an excellent complement to Christos Nikolaidis.

Best for: Detailed topic-by-topic revision notes and practice questions with model answers. The best written reference material after Christos Nikolaidis.
