FourtyFive Revision

FourtyFive is the adaptive IB revision platform built to make every minute count, allowing you to work smarter, not harder. Solve exam questions by hand using your iPad and Apple Pencil. When you submit your working, the app instantly marks it against official mark scheme criteria, showing you exactly where you secured or dropped points. If you get stuck, an interactive AI tutor is ready to provide targeted hints and step-by-step explanations for the specific part of the question you are struggling with. Every answer you write feeds into your personal mastery profile. Our algorithm tracks your performance down to the individual subtopic, removing the guesswork from your study schedule. Instead of wondering what to revise next, the app automatically diagnoses your knowledge gaps and builds a targeted practice queue around the exact areas hurting your grades. You get immediate access to a comprehensive question bank categorized directly by the latest IB specification. We currently cover Mathematics AA, Mathematics AI, Physics, Chemistry, Biology, and Economics at both Standard and Higher Levels. You can practice specific topics at your own pace, or simulate realistic pressure using the timed exam mode under authentic test conditions.
