Frequently Asked Questions
FourtyFive is an IB revision platform that helps you improve faster with personalised topic practice, exam-mode sessions, and progress analytics—so you always know what to do next.
Most question banks dump questions on you. FourtyFive tracks what you’ve done, spots your weaknesses, and recommends the next best topics and questions to raise your score.
FourtyFive is built for IB-style revision by topic and exam skills. Subject coverage depends on what’s currently live inside the platform, but the core experience is designed around IB markschemes and exam practice.
