Public Health Medicine (MFPH Part B oral)
Sit your MFPH B viva after rehearsing every answer out loud
Rehearse MFPH B Public Health viva scenarios out loud against a senior examiner who probes your reasoning. Get instant, examiner-style feedback on every answer — as many times as it takes to sound fluent.
What is the MFPH B viva, and how do you practise for it?
The MFPH B viva is an oral exam where you defend your clinical reasoning out loud to a senior examiner. The most effective preparation is repeated spoken rehearsal — with MedMock you practise viva-style questioning against an AI examiner and get instant, examiner-style feedback on every answer.

You can know the medicine and still freeze in the room
The MFPH B viva rewards fluency under pressure. It is not enough to know the answer — you must articulate it clearly and in a structured way, while a senior examiner interrupts and probes further.
That ability comes only from rehearsing out loud against someone who challenges you. Yet willing seniors are scarce, mock vivas are rare, and rehearsing silently develops none of the fluency you need on the day.
MFPH B viva practice, on demand
Six 8-minute examiner-led panel vivas testing epidemiological reasoning, critical appraisal, health promotion communication, policy analysis, public health ethics and leadership, and outbreak / incident management — anchored to the Faculty of Public Health Part B curriculum, UKHSA / OHID / NHS England structural frameworks, and named UK evaluations.
MedMock gives you a senior examiner who probes your reasoning, available 24/7. Pick a question, have a genuine spoken conversation, and get instant, examiner-style feedback the moment you finish — scored against what genuinely matters in the MFPH B. No rota conflicts, no study partner, no waiting your turn. Simply practise whenever you have ten minutes.
How it works
Choose a question
Pick from the real MFPH B questions — all 6 of them, or let MedMock surprise you the way exam day will.
Have the conversation
Speak naturally, out loud. The AI examiner listens, follows up and probes further, exactly like the viva.
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.
Why candidates practise with MedMock
Practise out loud, any time
No study partner, no booking, no rota clash. Open MedMock at 6am or midnight and run a full question in minutes.
All 6 questions, endless variations
You will never simply memorise answers. Each run is different, so you build the real skill — adapting in the moment.
Examiner-level feedback in seconds
Know exactly where you lost marks and how to address it, instead of guessing why a mock session went poorly.
Turn nerves into muscle memory
By the time you sit the MFPH B, the format feels familiar — because you have already done it dozens of times.
A fraction of the cost of courses
Avoid the hundreds of pounds you would spend on a one-off exam course, and practise unlimited scenarios instead.
Practise anywhere, from your phone
On a break, during the commute, between jobs on the ward — your preparation goes wherever you do.
Practise every station
MedMock covers the questions you will face in the MFPH B viva. Rehearse each one until it feels routine.
Epidemiological Data Interpretation
Interpret incidence / prevalence data verbalised from a briefing pack — describe trends, identify data limitations (denominator, coding, ascertainment), reason via Bradford Hill, and propose proportionate public health interventions.
Research Methods Critique
Critically appraise a summary of a public health study — name the study design, apply CASP / RoB 2 / CONSORT or STROBE, discuss internal and external validity, confounding, and applicability to UK policy.
Health Promotion Communication
Deliver key messages from a national health-promotion campaign to a lay community-group representative. Tested on COM-B-anchored behaviour-change reasoning, co-design, lay-audience register, and named UK delivery routes.
Policy Analysis & Advocacy
Advise a senior manager on a draft public-health policy proposal — structured options appraisal with equity (Marmot), feasibility, hypothecation, monitoring framework, and a named advocacy coalition strategy.
Ethical Dilemma & Leadership
Discuss a public-health ethical dilemma (typically resource allocation, compulsory treatment, or pandemic prioritisation) via Daniels' Accountability for Reasonableness — equity reasoning, dissent handling, transparent decision-making.
Emergency Response & Incident Management
Lead the public health response to an outbreak or environmental incident — UKHSA CDOM framework, OCT structure, case definitions, control measures, equity, IHR 2005 escalation, and the after-action / learning loop.
Example scenarios
A sample of the scenarios you will practise — each plays out as a live, spoken conversation, not a script to read.
“Discuss interpretation of cancer incidence data showing rising rates in young adults — Bradford Hill reasoning, data limitations of the briefing pack, and proportionate public-health interventions.”
“Deliver the key messages of a forthcoming national smoking cessation campaign to a sceptical tenants'-association representative from a low-income community. Use COM-B framing.”
“Advise the Director of Public Health on a draft extension of the Soft Drinks Industry Levy — four-lens options appraisal, equity argument, advocacy coalition strategy.”
“Handle a resource-allocation dilemma between extending bowel cancer screening to age 45 and rolling out lung cancer screening to additional eligible cohorts — apply Daniels' Accountability for Reasonableness.”
“Lead the outbreak control team response to a measles cluster in a school — UKHSA notification, OCT structure, case definitions, PEP timing, equity considerations, IHR 2005 escalation.”
MFPH B practice — your questions answered
How realistic is MedMock's MFPH B practice?
Every scenario is built around the real MFPH B viva format and the domains examiners assess. You speak out loud and the AI examiner probes your reasoning, so it feels far closer to the day than reading notes or rehearsing silently.
How does the feedback work?
As soon as you finish a question, MedMock gives you instant, examiner-style feedback and a score — highlighting what you did well, what cost you marks, and exactly what to work on next.
Can I practise specific MFPH B questions?
Yes. You can pick any of the 6 questions to drill a weak area, or run a mixed set to simulate the real exam.
Do I need a study partner or a fixed time slot?
No. That is the point — MedMock is available 24/7 and you practise alone, out loud, whenever it suits you. No coordinating diaries, no waiting for a course date.
Is MedMock right for me if I am sitting the MFPH B?
If your MFPH B exam involves speaking — defending your reasoning to an examiner — then spoken rehearsal is exactly what MedMock is built for.
How much does it cost?
Far less than a one-off exam course, with unlimited practice. Everyone starts with a free trial — no card required — so you can see how it works before paying. See current options on our pricing page.
