Cambridge Medicine Interview
Two science interviews at your applied college, twenty to thirty minutes each, and no written test in the room
Two science interviews at your applied college, twenty to thirty minutes each, and no written test in the room
You are handed a graph of oxygen dissociation curves and asked what happens to haemoglobin's affinity for oxygen at altitude. You answer. The interviewer then moves one variable and asks which part of what you just said still stands. That second question is the interview. A Cambridge Medicine panel is not auditing your syllabus; it is watching what a mind does when it meets something it did not prepare for and has to keep talking. Candidates who arrive with a polished account of their personal statement are wrong-footed by this. Candidates who can state an assumption, follow it, and give it up when the evidence moves are the ones who leave with offers. This page sets out one such exchange in full: the question as a panel would put it, the follow-ups they would use, and a reply that starts out wrong and has to be repaired in front of them.
A Cambridge Medicine panel moves fast between registers: a mole calculation on blood chemistry one moment, a pedigree diagram the next, then a question on confidentiality that has nothing to do with either. The Medicine pack mirrors that spread, pairing kidney and fetal-circulation physiology with the ethics scenarios a panel actually raises, euthanasia included. Medicine doesn't come with a free sample, so this paragraph does the job a sample would do elsewhere.

Get the Medicine pack — £180Cambridge Medicine interviews are conducted at college level, which means the format, style, and emphasis can vary between colleges. Most candidates receive two interviews, typically on the same day or across consecutive days, each lasting around 20 to 30 minutes. Both interviews are usually science-focused, though one may lean more heavily into problem-solving and the other into biological reasoning or clinical scenarios. A small number of colleges may conduct a third interview in borderline cases.
What interviewers are consistently looking for — regardless of college — is intellectual flexibility. They want to see a candidate who can take a concept they understand and apply it somewhere unfamiliar. They are not looking for medical knowledge beyond A-level; they are looking for the kind of scientific curiosity and analytical rigour that suggests a student will thrive in Cambridge's research-intensive environment. The supervision system at Cambridge, where students meet weekly in very small groups with subject experts, demands exactly this quality: the ability to engage critically with ideas rather than simply absorb them.
| Format | Panel interviews at your applied college, not MMI stations |
|---|---|
| How many | Usually two. A third happens only where a college is undecided, and is not standard |
| Length | About 20 to 30 minutes each |
| Who is in the room | Usually two academics |
| Emphasis | Both interviews are normally science-focused |
| Written test at interview | None. Cambridge sets no written paper at the interview stage |
| UCAT | Required, and used for shortlisting. For 2027 entry Cambridge reads the overall cognitive subtest score with the situational judgement section left out, and publishes no minimum |
Thinking aloud is not just permitted — it is expected. An interviewer who hears silence followed by a confident answer learns very little. An interviewer who hears a candidate work through a problem, identify where their reasoning breaks down, and adjust their approach in response to a prompt learns a great deal. The willingness to say "I'm not sure, but if I think about it from first principles..." is not a weakness. It is precisely what Cambridge tutors are trained to reward.
The following questions are representative of the kind of problems Cambridge Medicine interviewers use. They are not trivia. Each one is designed to reveal how a candidate reasons, not what they have memorised. A longer treatment of several of them, written for the same panel format, sits in the guide to Cambridge Medicine interview questions with science problem-solving and reasoning model answers. The fifth of them is taken below through the three layers a pack uses.
When approaching any of these questions, resist the urge to reach for a conclusion immediately. State your assumptions. Identify what you know and what you are inferring. If the interviewer pushes back, do not abandon your reasoning out of anxiety — engage with the challenge and revise only where the logic demands it. Changing your answer because an interviewer raised an eyebrow is a red flag; changing it because they introduced a piece of evidence you had not considered is exactly right.
An expert pack carries three headings in a fixed order. Questions is the question with nothing beneath it. Prompts is where the interruptions live. Suggested answers is one person reasoning in their own voice, from the first thing they said to the last. What follows does that to the fifth of the questions listed above. Attempt it before you read past the Prompts; the walkthrough is written for afterwards.
“If natural selection favours survival and reproduction, why does ageing exist? Every organism you can name gets worse at both as it gets older. Selection has had several hundred million years to remove that. Why is it still here?”
You are given the sentence and nothing else: no species, no numbers, no working definition of ageing. Somebody who has never read a word about senescence can still answer it, and that is the point. Reading around the topic would only supply a memorised exit. What the panel wants to watch is a person handling a premise that appears to refute itself, live.
In roughly this order, and never all at once:
Group benefit was my first answer, and one cheat destroys it. I began by making ageing purposeful: organisms wear out and die so that resources pass to the young, and the population does better for it. The interviewer asked what would happen to a mutant that skipped the arrangement and carried on reproducing. That mutant leaves more offspring than every neighbour dying on schedule, so its lineage spreads and the arrangement is gone within a few generations. A trait any cheat can profit from is not something selection between individuals can build. Worse, I had explained ageing by quietly granting that organisms are built to die — which is the thing I was being asked to account for.
The second prompt hands you a rate, and the argument is entirely in pushing it through. Ten per cent of a cohort dies each year from causes unrelated to ageing. The fraction still alive after n years is 0.9 raised to the power n. At ten years, 0.910 = 0.349, so about 35 in every 100 remain. At thirty years, 0.930 = 0.042, about 4 in every 100. The cohort is halving every 6.6 years, since 0.9 raised to 6.58 is one half.
Now put an allele into that population and let it act at one fixed age. Acting at ten, it is expressed in 34.9 per cent of everyone born. The identical allele acting at thirty finds only 4.2 per cent of the cohort still alive to express it. Taken before either figure was rounded, 0.3487 ÷ 0.0424 = 8.2: the same allele is about eight times more visible to selection at ten than at thirty, and nothing about the allele changed — only how many were left to carry it.
That is the mechanism, and no property of ageing was assumed to reach it. Selection’s grip on a trait weakens as the age at which the trait acts rises, because the audience shrinks. Two things follow. Deleterious mutations that act late are removed inefficiently and accumulate, the pressure against them being a fraction of the pressure against an early one. And an allele that raises reproductive output early while imposing a cost late can be positively favoured: the late cost arrives at an eight-fold discount and the early benefit does not. That is the allele the fourth prompt was asking for. Ageing on this account is not a programme. It is what collects in the shadow where selection cannot see well.
One number dissolves all of it, and it is better named by you than found by them. Everything above needs extrinsic mortality high enough to hollow out the older ages. Set that rate near zero and the survivorship curve stays flat: almost the whole cohort is still present at thirty, and the eight-fold discount collapses towards one. Saying so is not a concession, it is the strongest move left, because it turns the argument into something that can be checked — lineages that have found a way to cut extrinsic mortality, through flight, through armour, through living somewhere nothing can reach them, should then age more slowly than body size alone would predict.
An interviewer listening to that has three separable things in front of them. First, the circularity: group benefit accounts for ageing only once you have granted that organisms are built to die, and an argument that assumes its own conclusion has not failed at the edges. Second, whether the arithmetic was performed or gestured at. “Selection weakens with age” is the conclusion; 0.910 set against 0.930 is the derivation, and only the second of those produces 8.2. Third, who raised extrinsic mortality. Volunteered, it reads as a candidate who has already tested their own case to destruction; extracted under questioning, it reads as one who had not thought to.
Ten of these, and the two layers under each one
The Medicine pack sets ten questions and gives every one of them the same three layers you have just read: the question by itself, the interviewer’s prompts held separately, and a worked answer in the first person. Its range is scientific reasoning and unfamiliar data, ethical scenarios, and the personal-statement follow-ups. Nothing in it is written as an MMI station, because Cambridge does not run them.
Medicine opens no sample file; only nine subjects do. Ten questions is enough to take one at a time — attempt it cold, then read the answer against what you actually said — rather than going through the file end to end in one sitting and retaining none of it. £180, one payment. Two packs take 10% off and three take 20%, applied at checkout without a code. The catalogue also carries Physiology under Biology, and Biochemistry for Medics under Chemistry.
Get the Medicine pack — £180Cambridge sets no written admissions test at the interview stage. The UCAT does its work earlier: it is required, it helps decide who is called to interview, and for 2027 entry Cambridge reads the overall cognitive subtest score with the situational judgement section left out. No minimum is published, which means every “safe score” figure circulating for Cambridge Medicine was produced by someone other than Cambridge. By the time you are in front of the panel, though, the UCAT is spent. Nothing about it is re-examined, and nothing about it rescues a conversation that goes badly. That concentration of weight onto two conversations is why the interview repays structured preparation more than almost any other part of the application.
It also means the two stages need separate preparation, because the skills barely overlap. UCAT practice is silent, timed and multiple-choice; it rewards arriving at one answer fast and never rewards showing the route. A Cambridge Medicine interview is spoken, unhurried and open-ended, and the assessment falls on the reasoning between your first answer and your third. No amount of pattern-matching under a clock builds that.
The prompts are the layer you cannot write for yourself
A question on its own is the easy half, and most applicants already have more questions than they will ever work. The half nobody can supply for themselves is the follow-up an interviewer has ready for the answer you were about to give: to write that, you would have to know in advance where your own reasoning is going to give way. It is kept on a page of its own so it arrives only once an answer is already out of your mouth.
The Medicine questions run across physiology and unfamiliar data, ethical scenarios, and the personal-statement follow-ups — the ground every college draws on, rather than a bet on one college’s emphasis.
Medicine expert pack — £180Super-curricular engagement is not optional for Cambridge Medicine. Interviewers expect candidates to have read beyond the A-level syllabus — not to accumulate facts, but to demonstrate genuine intellectual appetite. The most useful preparation involves:
If you are also applying to the other university, the Oxford Medicine interview page sets out how that process differs. The two share a commitment to academic rigour but diverge meaningfully in interview style and structure.
The most damaging mistake is preparing to perform rather than preparing to think. Candidates who rehearse polished answers to anticipated questions often freeze when the question takes an unexpected turn — which at Cambridge, it almost always does. A related error is treating silence as safer than uncertain reasoning. Cambridge interviewers are not looking for certainty; they are looking for intellectual honesty and the ability to work under pressure.
A second common mistake is neglecting the science in favour of the personal statement. Many candidates spend weeks refining their ability to discuss work experience and motivations, then struggle when asked to explain the mechanism of enzyme inhibition or interpret an unfamiliar graph. Cambridge interviews are science interviews first. Your motivations matter, but your ability to reason through a biological problem matters more.
Finally, candidates sometimes underestimate college variation. The style of questioning at one college may differ noticeably from another, and a plan built for a generic Cambridge Medicine interview underprepares whichever emphasis you actually meet. The defence is not to guess which college leans where. It is to practise the reasoning every college draws on — physiology from first principles, an unfamiliar graph or pedigree, an ethical scenario with more than one defensible answer — so that the emphasis you meet is one you have already worked in some form.

Most Cambridge Medicine candidates have two interviews, both typically held at their applied college. Each interview lasts around 20 to 30 minutes and is usually conducted by two academics. In some cases, a college may arrange a third interview for candidates they are undecided about, though this is not standard. Both interviews are generally science-focused, and you should prepare for problem-solving questions in each one.
Cambridge interviewers want to see evidence of genuine intellectual curiosity beyond the A-level curriculum. The most valuable preparation is reading science writing that challenges you to think critically — and being able to discuss it analytically, not just describe it. Understanding the mechanisms behind biological and chemical processes at a deeper level than the syllabus requires is also essential. Work experience is expected, but it is your ability to reflect on and reason about what you observed that Cambridge values, not the experience itself.
Yes — but only if they replicate the actual conditions. A mock interview where you are asked predictable questions and given gentle feedback will not prepare you for a Cambridge interview. What you need is practice being interrupted mid-explanation, being pushed on assumptions you thought were solid, and continuing to reason clearly when you are uncertain. The version of that you can build alone is limited but real: take an unfamiliar question, answer it out loud at full length before you read anybody else's answer to it, and record yourself doing it. What comes back is rarely the reasoning, which is usually better than you feared. It is the length of the silences where you were thinking instead of talking.
Cambridge Medicine interviews are more academically intense than those at most other UK medical schools. Where many universities focus on communication skills, empathy, and situational judgement, Cambridge focuses primarily on scientific reasoning and intellectual flexibility. There is less emphasis on clinical scenarios and more on working through unfamiliar problems from first principles. The closest comparison is Oxford, though the two differ in structure and style. Most other medical schools use the interview to assess whether you are a suitable future doctor; Cambridge uses it to assess whether you are a suitable Cambridge student — which is a meaningfully different question.
Do the ageing question the way it is meant to be done: hide everything from the Prompts down, give it a real attempt out loud, then take the follow-ups one at a time. The Medicine pack page carries a second worked question, on what a doubled creatinine reading does and does not tell you, at the same length. Nine subjects — biology, chemistry, engineering, geography, german, history, maths, physics and vet med — also open a free sample file; Medicine is not one of them.
91% of our students achieve their desired grades. Rated Excellent on Trustpilot. That is the company’s rating, not a rating of this pack.
Ten questions, and each one appears three times under three headings in a fixed order. Under Questions it stands alone. Under Hints are the interviewer’s follow-ups for that question, meant to be taken one at a time. Under Suggested answers, one person reasons the whole thing out in their own voice — not a scheme awarding marks. Keeping the three apart is the design: nothing on the page tells you where a question is going until you have already tried it. Coverage is scientific reasoning and unfamiliar data, ethical scenarios, and the personal-statement follow-ups, set as panel questions rather than MMI stations. £180, one payment.
A printed file cannot make you do the one thing it is built around. The layout asks you to attempt a question before you reach the guidance — which is why the Suggested answers sit apart from the question rather than under it — but nothing stops you reading the answer first. Once you have, that question is spent: you will never meet it again not knowing where it goes. With ten questions, that is a tenth of what you paid for, gone in the seconds it takes to scroll. Print it, and work down the page with a sheet of paper over the rest.
It will not, and a pack that promised to would be worth less. Cambridge requires the UCAT for shortlisting — for 2027 entry the overall cognitive subtest score, with the situational judgement section left out, and no minimum published — but that is settled before an interview invitation arrives. The pack is interview material: physiology and unfamiliar data, ethical scenarios, and the personal-statement follow-ups. It will not move a UCAT score, and the two stages reward different skills. £180 covers the Medicine pack alone.
Three headings, in this order: the question by itself, what the interviewer would say next, and a full answer in one person’s voice. They are held on separate pages, so a question arrives with no help attached. Medicine opens no sample file — only nine subjects do — so the question above was written out here in that shape instead.
