What you actually do here
- Adaptive tests. Build a paper from the bank, or let it weight questions toward the regions you keep missing.
- Spaced-repetition flashcards. After each card you rate Not at all, Somewhat, or Very confident. Fumbled cards come back sooner; the schedule is an SM-2 variant we run ourselves.
- Guided revision. Region by region, with the structure's location, relationships, a recognition cue, and a pearl — the same fields written on the question, not a chatbot essay.
- CR1 simulation. Exam conditions: 100 questions, 90 minutes, mixed cases, the same marker as a live paper.
- Progress. Recent test performance, clear trends and body-region results, with separate flashcard and revision progress to help you choose what to practise next.
The library
211 published questions right now — 7 radiographs, 145 CTs, 41 MRIs. MRI is a small set (head axials), not a second CT library. We add cases as they clear attribution; we will not invent a catalogue we do not have.
Imaging is credited on every question and on the attributions page. Datasets such as TCIA and FracAtlas stay named there because the licences require it, not as decoration.
Free trial
A free trial of 24 hours comes after signup and card setup. Prices are in GBP. See the pricing page.
