I-Passed is a free revision platform for IB, Cambridge IGCSE, AQA GCSE and AP students. Across Biology, Chemistry, Physics and Maths you get thousands of topic-tagged questions, written for the current syllabus, with instant feedback and worked explanations — so every practice session moves you closer to the grade you want.
Choose exactly the topics you're studying and build a custom quiz in seconds. Questions are tagged to the current IB, IGCSE, GCSE and AP syllabuses, so there's no outdated material to wade through.
Reveal answers only after you've tried to recall them, and let spaced-repetition flashcards focus your time on the things you keep getting wrong.
Create a free account to save your topic scores and quiz history across every device, and benchmark yourself with diagnostic assessments.
You can practise without one — but a free account turns scattered quiz sessions into a picture of exactly where you stand.

Every quiz you finish feeds a game-style radar of your strengths — across all your subjects, drilling down from subject to theme to the individual topic you keep missing.
Biology is live now across all four boards, with Chemistry, Physics and Maths rolling out next. Each course follows the current specification — AQA, Cambridge, IB and College Board — and comes with study notes, flashcards, crosswords, a daily word game and indexable practice questions. Pick your board above to begin — it's completely free.
Effective revision isn't about re-reading notes until they feel familiar — that familiarity is a trap. The fastest way to lock knowledge in is active recall: forcing your brain to retrieve an answer before you check it. Every quiz on I-Passed is built around that idea. Start by choosing a single topic you find shaky rather than a whole paper, answer 10–20 questions with the answers hidden, and only reveal each explanation once you've committed to a response — even a wrong guess strengthens the memory more than passive reading. Then let the flashcards and diagnostic tools do the scheduling for you, so the material you keep missing comes back more often and the material you've mastered quietly steps aside.
