Question banks
Practice Part 1 and Part 2 in the formats you'll actually encounter.
Video tutorials
Build the knowledge behind the questions with curriculum-mapped teaching.
Track your progress
See where you've performed well — and where to focus next.
AI that speeds things up and sharpens how you learn — never the final word.
AI drafts content, personalises your practice, marks your answers and even role-plays patients in live voice consultations — but it never decides what's correct. A clinician always checks before anything reaches you.
Faster, not shorter
AI drafts questions and rubrics so specialists spend their time reviewing, not typing from scratch.
Sharper practice, instant feedback
AI reasons over your attempt history to tell you what to practise next, and marks free-text answers the moment you submit.
Voice consultations with an AI patient
Practise history-taking and clinical reasoning out loud, marked against a clinician-written rubric.
Checked at every step
Every AI draft and every AI mark is verified by a specialist before it reaches you.
A question bank - but better.
Question banks that follow the FRCPath format and difficulty, and every rationale is checked by a consultant clinical infection specialist before it goes live — not pulled from a forum, not generated on the fly.
- Explanations for every option — why it's right, why the others aren't
- Detailed explanations where a topic needs more depth
- Question-pace tracking against real exam timing
- Links to the guidelines and resources behind every answer

Bacteriadle: a new case every day.
Five tries, one organism. Each guess unlocks the next lab result — in the order results actually arrive on the bench — so working it out feels like running the case, not guessing a word.

Antimicrobial stewardship needs another pass
You're strong on Bacteriology, but Antimicrobial stewardship is both weaker and more heavily examined — that's where this week's practice will count most.
A weekly, personalised nudge, not just numbers.
Every week, we reason over your actual attempt history — weighted by real exam weighting for Part 1 — and tell you exactly what to practise and what to (re)watch next, rather than leaving you to read a grid of percentages and guess.
Know exactly where you stand, domain by domain.
Every question and video updates your position against the real curriculum map — so you know which domains are exam-ready and which need another pass, for both parts of the exam.
Be first through the door.
Create a free account for the full question bank, video tutorials and progress tracking across both parts of the exam.
