Why short reels work

Each app is built on memory research that has held up for decades, and on a plan that is shaped around you. Here is what that means in plain words.

1. Revision timed to your memory. The open-source FSRS spaced-repetition scheduler gives each fact its own next review ("Next in 6 days"), just before you would forget it. Spacing: Cepeda et al., 2006 and 2008.
2. Recall, not rereading. Questions inside every chapter and a Test me button: you answer before you see the explanation. Retrieval practice: Roediger and Karpicke, 2006.
3. Mixed revision. Practice and mini mocks mix questions from different chapters, like the real paper. Interleaving: Rohrer and Taylor, 2007.
4. Look-alike duels. The things you mix up, side by side, until you can tell them apart. Comparing categories: Kornell and Bjork, 2008.
5. Every option explained. In past papers, why the right answer is right and why each wrong one is wrong. Feedback after tests: Butler and Roediger, 2008.
6. Your own plan. Built from your exam date and your minutes each day; Today shows what to do and why. Readiness from your own answers is an estimate, not a promise.

Research shows what tends to help most learners. No app can promise marks, a rank or selection.
