After the TARA: Preparing for Your Oxford Experimental Psychology Interview

Oxford Psychology (Experimental) is a BA of three or four years, UCAS code C830, with an intake of 49 and an entry requirement of A*AA. For 2027 entry every applicant must sit the Test of Academic Reasoning for Admissions, which runs from 12 to 16 October 2026. Shortlisted candidates are interviewed by two colleges on 14, 15 and 16 December 2026.

That first paragraph would have been wrong a cycle ago. Oxford's Experimental Psychology applicants had no written admissions test to sit, and most of the guidance still online was written on that basis. The course page now states the requirement plainly, and it changes what the autumn is for: there is a reasoning test in October and an interview in December, and the two are testing recognisably similar habits of mind.

Why Oxford's Own Psychology Interview Question Is a Problem-Solving Puzzle

Oxford publishes a set of sample interview questions supplied by the tutors who ask them, with a Psychology section among them. The Experimental Psychology example is not a question about memory, or the brain, or a study. It is a game.

A hundred people each put a pound into a pot. Each of them picks a number between 0 and 100. The pot goes to whoever picks the number closest to two-thirds of the average of every number chosen. What do you pick, and why? The interviewer who supplied it, Nick Yeung of University College, explains in Oxford's own commentary that he likes it because answering it draws on a range of skills the subject needs, partly numerical and analytical.

Work it and the shape of the thing appears. If you assume the field picks at random, the average is around 50, so two-thirds of it is about 33 and that is your answer. But everyone else can reason that far too, so if they all pick 33 the average is 33 and the winning number is two-thirds of that, about 22. Apply the same step again and you get about 15, then 10, then 7. Iterate to the end and everyone lands on 0, which is the equilibrium the mathematics points to and almost never the number that wins.

The interesting part is the last step, because it is the one that is actually psychological. Choosing 0 is the answer that assumes everyone else reasons perfectly and to the end. Real fields do not: they stop after one or two rounds. So the strong answer is not a number at all but a statement about depth of reasoning — how many steps you expect the other players to take, and therefore how many you should take yourself. That is a claim about other people's minds, made from a mathematical model, and it is exactly what a scientific psychologist does for a living.

Oxford says its Experimental Psychology tutors want to see that a candidate appreciates the scope of scientific psychology, can evaluate evidence, can consider issues from different perspectives, has a capacity for logical and creative thinking, and appreciates the importance of empirical evidence in supporting arguments. The guessing game reaches most of that list in a single conversation, and it needs no psychology content to start.

What the Scored Half of the TARA Actually Measures

The TARA is three modules, each lasting 40 minutes, and all three are compulsory for every Oxford applicant. Critical Thinking is 22 multiple-choice questions and Problem Solving is 22 multiple-choice questions. Candidates book an available Pearson test centre, use no calculator and no dictionary, and lose no marks for a wrong answer — UAT-UK states there is no negative marking, which makes leaving a question blank strictly worse than guessing.

Those two modules are scored separately, each on a scale from 1 (low) to 9 (high), reported to one decimal place. There is no pass mark; UAT-UK says so in terms.

The link to the interview is not a coincidence of scheduling. Problem Solving asks a candidate to get a defensible answer out of a situation that was not covered in any syllabus, under time pressure, with no formula to reach for. So does the guessing game above. The difference is that the test wants one option shaded on a screen and the interview wants the reasoning out loud, with a tutor interrupting it. A candidate who handled Problem Solving well has practised the reasoning already; what the interview adds is having to narrate it while someone argues back.

The Writing Task, and What It Is Not

The third TARA module is a Writing Task: one essay-style question chosen from three, with a word limit of 750 words, in the same 40 minutes as the other two modules. It behaves differently from them in a way that is easy to miss.

UAT-UK does not score it. Its own wording is that the Writing Task is not scored by UAT-UK, and that instead a copy of the response is sent to the universities where the candidate applied, for every course requiring the TARA. So the test returns two numbers and one document, and the document is the candidate's own prose.

Be careful what is concluded from that. Neither Oxford nor UAT-UK publishes who reads the essay, at what stage, or whether a college tutor has it in front of them during an interview. No source was found that says so, and this page does not claim it. What is published is enough to act on: the argument goes to Oxford, unscored, in the candidate's own words. Writing down which of the three questions was chosen and what line was taken, within a day or two of the sitting, costs ten minutes and removes the risk of being unable to reconstruct it in December.

Oxford asks for no separate submitted written work for this course, so the Writing Task is the only piece of timed writing the university receives through the admissions test route.

14, 15 and 16 December 2026: Oxford's Published Interview Dates

Oxford has published its 2026 interview timetables, and Psychology (Experimental) has a three-day block: first and second college interviews take place on Monday 14, Tuesday 15 and Wednesday 16 December 2026. The same three days are used for Psychology, Philosophy and Linguistics, which matters for anyone holding an application to both.

Two details are worth planning around. Oxford's course page promises shortlisted candidates at least one online interview, while the timetable schedules first and second college interviews — so prepare for more than one conversation, not one. And Oxford commits to at least 24 hours' notice of any additional interview, which is short notice for anything that needs arranging.

Counting from the end of the October sitting on 16 October 2026 to the first interview day on 14 December 2026 gives 59 days. That is our arithmetic from two published dates rather than a figure Oxford states, and almost all of it falls before either the score or the shortlisting letter arrives.

How to Read 34% Interviewed and 12% Successful Once You Are Shortlisted

Oxford publishes three figures for Psychology (Experimental) on the course page, as a three-year average across 2023 to 2025: 34% of applicants are interviewed, 12% are successful, and the intake is 49. Both rates are shares of all applicants, which is the wrong denominator for anyone holding an interview invitation.

Dividing 12 by 34 gives approximately 35%. That is our arithmetic on Oxford's two published rates, not a figure Oxford states, and because both inputs are published rounded to whole percentages the result is approximate. Read carefully it says that about two-thirds of the people who reach an Experimental Psychology interview do not receive an offer, and that all of them cleared the same paper stage.

Set beside Oxford Human Sciences, which interviews 56% of its applicants and admits 16% on the same three-year basis, Experimental Psychology interviews a smaller share and converts a larger share of the ones it sees. A harder shortlist, in other words, and then a slightly better room. Our page on Oxford Human Sciences after the TARA works that course's calendar through in the same way.

Which Pack Covers Which Half of an Experimental Psychology Interview

An Experimental Psychology interview pulls in two directions. One is experimental: study design, confounds, what a result can and cannot show, the physiology underneath a behavioural finding. The other is social and behavioural: why people act as they do in groups, how a claim about a population is supported, what counts as evidence for a statement about human beings.

The Biological Sciences pack covers the first. It works through warning colouration and mimicry, blood-vessel resistance, the Meselson-Stahl DNA-replication experiment and enzyme-inhibition kinetics — experiments, mechanisms and the reasoning that connects them. There is a free biology sample listed for it on the hub, so the format can be read before anything is bought.

The HSPS pack covers the second: how Nozick's Wilt Chamberlain argument bears on redistribution, why the incest taboo varies by culture, and whether social media strengthens or weakens democracy. Its listing says there is no free sample, and this page will not imply otherwise.

Both are ten questions with worked answers, at £180 each, and both are bought on the Oxbridge interview questions hub rather than here — this page describes them and sends you there. They arrive as PDFs: payment goes straight to a download page rather than an email, and that page and its links stay live for 48 hours, so the files are worth saving immediately. The hub lists 30 subject packs and nine free samples in total and applies its discount automatically when more than one pack is bought.

For the interview itself rather than the test, our Oxford and Cambridge Psychology interview guide works through a study critique and a framework for ethical scenario questions, and the wider Oxbridge interview guides cover every major subject.
