## How a practice session works

1. **Choose a station** — Choose the kind of question or scenario you want to rehearse — ethics, motivation, a role-play, and more.
2. **Have the conversation** — Speak naturally, out loud. The AI interviewer listens and asks the demanding follow-ups, just as a real interviewer would.
3. **Get instant feedback** — The moment you finish, you get specific, examiner-style feedback and a score — what you did well, what cost you marks, and precisely what to fix before the next attempt.

## About MedMock

MedMock is a web app for practising the spoken parts of UK medical and dental exams and interviews out loud. The candidate talks; an AI patient, examiner or interview panel answers in real time by voice; and when the station ends MedMock marks the performance against that exam's assessment domains and shows the model answer.

It covers 104 spoken exams and interviews — OSCEs, vivas, structured oral exams, simulated consultations, and specialty-training and consultant interviews. It does not cover written or multiple-choice papers, and it is not a question bank.

It was founded by Mr Sam Nahas, MBBS BSc MEd FRCS (Tr & Orth), a practising consultant orthopaedic surgeon in the UK, with co-founder and CTO Arjan Jandu. It is operated by VirtualPatients Ltd (company no. 16303492).

Pricing: a one-off £5 taster of 30 credits to try it (not a subscription, one per account), and a monthly subscription from £20 to £129 depending on the exam (student exams cost least, fellowship exit exams and consultant interviews most), or £199 to £275 for the Intensive plans, which carry more credits. One credit is one minute of spoken practice, or two typed exchanges, and where the examiner or patient speaks first, that opening line is free. Examiner scorecards, mark schemes and model answers for finished sessions are included at no extra credit cost. Subscriptions can be cancelled at any time.

It runs in a web browser on a laptop or phone; spoken practice needs a microphone. There is no public demo: practice needs an account with credits, usually from the taster or a monthly plan.

MedMock is for adults aged 18 or over. Sign-up asks every new account to confirm it.

MedMock is a revision tool. The patients, examiners and cases are fictional and AI-generated; it is not clinical guidance and is not affiliated with or endorsed by any Royal College, the GMC, the GDC or any examining body.
