Both universities publish practice advice, and it is more modest than what the mock-interview industry sells
Book a Free ConsultationOxford says a practice interview “doesn’t have to be a formal mock interview”. Cambridge asks for one, but adds a criterion most families miss: ideally with “someone who doesn’t know you well”. Both publish sample questions you can legitimately use, and Oxford’s code of conduct explains why no honest list of this year’s real questions exists. Around 10,000 candidates interview each December; here is how to rehearse for it at home.
A home mock needs material, not just a willing interviewer. Our subject packs (£180 each) give the person asking the questions a script with worked reasoning and technique notes from specialist subject tutors — so they can prompt usefully in a subject they do not know. Nine subjects have a free sample.

Cambridge’s interview preparation guidance is direct: “Have a practice interview. Ideally ask a teacher or someone who doesn’t know you well so that you can practise expressing your ideas and opinions. Alternatively, you could ask yourself questions for half an hour.”
Oxford, in its guidance for applicants, sets the bar lower still: practice conversations about your subject “don’t have to be formal ‘mock interviews’ — instead they could be chats with teachers, friends, or family.” And if there is nobody at all: “why not record a vlog to practise speaking, or hold an imaginary interview in your head, or even talk to the cat!”
Neither university describes anything a family cannot arrange. What both are actually asking for is that the first time you explain your reasoning out loud to another person is not in December. The formality is not the point; the speaking is.
Cambridge’s phrase — “someone who doesn’t know you well” — is the most useful five words on this subject, and it rules out the person most households reach for first.
| Who asks the questions | What it is good for | What it cannot do |
|---|---|---|
| A teacher in the subject | Cambridge’s first choice; can push on the content and tell when an answer is thin | Usually knows the candidate well, so fills gaps automatically |
| Someone who does not know you well | Cambridge’s stated criterion — hears the gaps a familiar listener smooths over | May not know the subject well enough to follow up |
| A parent | Always available; fine for the format, the timing and the technology | Knows your shorthand; hard to press on a subject they have not studied |
| Yourself | Cambridge’s explicit fallback: question yourself for half an hour | No interruption, and interruption is the thing being rehearsed |
| Nobody available | Oxford’s suggestion: record a vlog, or hold an imaginary interview | Speaking practice only |
The reason is not that parents are bad at it. It is that a listener who knows you fills your gaps automatically. When a candidate says “and then obviously you’d get the second effect”, a parent who has heard the enthusiasm for six months nods along; a stranger asks what the second effect is, and the candidate discovers they had never actually said it. That discovery is the entire value of the exercise, and familiarity suppresses it.
The practical compromise most families land on works well: a parent runs the format, the timing and the technology, and somebody else — a teacher, a family friend in a vaguely related field, a tutor — runs at least one session on the subject itself.
If nobody at home can push back on the subject itself, that is exactly the gap our specialist tutors fill: someone who does not know the candidate, does know the subject, and will keep asking why.

Accepting an Oxford interview invitation means agreeing to a code of conduct, and its first clause is: “I agree not to share in any form the content of interviews with others and including but not limited to candidates or teachers at my school/college or at any another school/college. This includes discussing the content of interviews verbally.”
Follow that through. Every candidate who sat an interview last December gave that undertaking. So a list advertised as this year’s real questions is one of three things: old, invented, or somebody breaking a promise they made. None of the three is good practice material, and the last is not something to build a rehearsal on.
| Source of questions | Legitimate? | Why |
|---|---|---|
| Oxford’s published sample questions | Yes | Published by the university, “direct from the tutors who conduct the interviews”, with their marking notes |
| Oxford’s demonstration interview videos | Yes | Tutor introduction, a real sample interview with a current student, then a tutors’ commentary |
| Published question packs and guides | Yes | Built from published material and subject knowledge rather than from leaked content |
| “Real questions from this year” lists | No | Every candidate agreed “not to share in any form the content of interviews”, so these are old, invented, or a broken undertaking |
The good news is that the legitimate sources are better than the illicit ones anyway. Oxford publishes sample questions “direct from the tutors who conduct the interviews” with the tutors’ own explanation of what each question is for — which a remembered question can never carry. It also publishes demonstration interview videos: an introduction from the tutors, a sample interview with a current student, and then a commentary in which the tutors “discuss how they feel the interview went”. That commentary is the closest thing to a mark scheme a candidate will ever see.
Take the structure from what Oxford’s published questions actually do, because they are consistent about it.
Open with something unfamiliar built on familiar material. The published questions are answerable from A-level content but have never been set as an A-level question. Do not ask the candidate to recite; ask them to apply.
When they stall, widen the question. Oxford describes prompting a stuck candidate to “describe more generally” the underlying principle before returning to the specific case. At home the version of this is “what would you need to know to make a start?” It is not a hint, and it is not a rescue.
Insist on the working, not the answer. Oxford tells candidates their “final answer is only part of what they find out”, and describes a good approach to one of its questions as “first consider the individual functional groups separately and then to discuss the compound as a whole”. Parts, then whole, said aloud.
Always ask the second question. This is where most home mocks stop and most real interviews begin. Owen Lewis, who interviews for Biology at Brasenose, describes his: “Once students have come up with a plausible theory, I’d follow up by asking them how they would go about testing their idea. What sort of data would they need?” Any plausible answer can be followed with “how would you check that?”, and it takes no subject knowledge to ask.
That last point matters for a non-specialist interviewer. You do not need to know the subject to ask the three questions that do the work — why, how would you test that, and what would change your mind. Our guide to thinking out loud in an Oxbridge interview covers what a good spoken answer sounds like from the candidate’s side.
My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
Interviews are online, so part of the rehearsal is the setup. Cambridge lists what to do: pick a quiet space, make sure the device has a full battery, “test that your webcam, microphone and internet work”, and “have a pen and paper in case you need to make notes or show how you’ve worked out a problem to the interviewers”.
For science and maths candidates it adds a specific instruction: “practise using a stylus and tablet to annotate a shared document or whiteboard” if the College has said one is needed. And a detail worth knowing before you buy anything: “Your College may also run a ‘tech check’ session to help with this.”
Oxford sorts its courses into three technology tiers, and which one you are in determines whether a home mock needs a shared whiteboard at all. Tier 1 is video only; tier 2 adds an interactive whiteboard; tier 3 adds handwriting capture through a stylus. Our guide to Oxford’s interview technology tiers lists which courses sit in each, and a tier 3 candidate should be writing on a shared board in at least one rehearsal.
Run the free sample as your first home mock: real questions, worked answers to check against, nothing to pay. If it goes well, the full subject pack (£180) gives you enough material for several more sessions, written by specialist subject tutors.

Do not coach towards a preferred answer. Cambridge tells candidates “you can answer the questions in your own way, you don’t need to say what you think the interviewers want to hear”. An interviewer at home who visibly wants a particular answer trains the candidate to hunt for it, which is the opposite of the habit being assessed.
Do not end the question at the wrong turn. A wrong answer is where a real interview becomes interesting. Oxford also reminds candidates they can ask for a question to be repeated, so a candidate who has misheard should be allowed to say so rather than answer the wrong thing.
Do not rehearse a clever closing question. Oxford is explicit: if you are given the chance to ask your own questions at the end, “this does not form any part of your assessment”. Time spent polishing one is time not spent on the part that is marked. If you want the full picture of what is, see what Oxbridge interviewers actually mark.
Oxford says not. Its guidance describes practice conversations about “your subject and your thoughts about what you’ve seen or read” and adds that “these don’t have to be formal ‘mock interviews’ — instead they could be chats with teachers, friends, or family.” Cambridge does recommend a practice interview, but its criterion is about who asks rather than how formal the setting is. What both are asking for is that you have spoken your reasoning aloud before December.
Cambridge is specific: “Ideally ask a teacher or someone who doesn’t know you well so that you can practise expressing your ideas and opinions.” That criterion quietly rules out the person most families use. Someone who knows you well fills in your gaps without noticing, so you never find out which parts of your explanation were missing. A stranger has to be told everything, which is the exercise.
You cannot get this year’s, and that is by design. Oxford’s code of conduct, which candidates accept with the invitation, includes: “I agree not to share in any form the content of interviews with others” — including verbally, and including with teachers. Any list claiming to hold current questions is old, invented, or a broken undertaking. What is legitimate is what the universities publish themselves: Oxford’s sample questions with tutor commentary, and its demonstration interview videos.
Long enough to be interrupted several times, which in practice means twenty to thirty minutes rather than five. Cambridge’s fallback for a candidate with nobody to ask is “you could ask yourself questions for half an hour”, which is a reasonable guide to the length of a single session. Two shorter sessions on different questions are usually more useful than one long one, because the first ten minutes of any mock are spent settling.
Prompt, not rescue. Oxford describes its own practice: “If a student struggles with a starting point we would prompt them to describe more generally the different kinds of interactions that hold molecules together and to comment on their relative strength.” The prompt widens the question rather than supplying the answer. At home the equivalent is asking “what would you need to know to start?” rather than offering the next step.
Yes, and Cambridge gives the checklist: a quiet space, a device with a full battery, a tested webcam, microphone and internet, and “a pen and paper in case you need to make notes or show how you’ve worked out a problem”. Science and maths candidates should “practise using a stylus and tablet to annotate a shared document or whiteboard”. Cambridge adds a detail worth knowing: “Your College may also run a ‘tech check’ session to help with this.”
Three things. Do not coach the candidate towards an answer you have decided is right — Cambridge says “you don’t need to say what you think the interviewers want to hear”. Do not let a wrong turn end the question; that is where the real interview starts. And do not rehearse a closing question to ask the tutor: Oxford states that if you are offered the chance, “this does not form any part of your assessment.”
Our specialist tutors are the thing Cambridge describes and most families cannot supply: someone who does not know the candidate but does know the subject, and will keep asking why. We work from published questions and the criteria faculties publish, and we tell you afterwards which criterion gave way first.
