Every IB Chemistry past paper, organised by session and timezone. Pick a paper below to open Paper 1A, 1B, and 2 at Standard or Higher Level, where each question has its own video going through it. Question counts are listed so you can plan a full timed sitting or drill a few questions at a time.
Sit the paper under exam conditions first, then come back and watch the videos for the questions you got wrong or guessed at. Paper 1A is multiple choice, Paper 1B is data-based, and Paper 2 mixes short-answer with extended response. HL papers add the higher level material on top of the core.
Work backwards from the most recent. November 2025 and May 2025 sit closest to the current syllabus, so they're the best guide to your own exam. Move to earlier sessions once you've used those up.
