Oxbridge Subject Preparation: Tests, Written Work and Published Odds for 2027 Entry

Oxford and Cambridge assess by subject, not by university. For 2027 entry that means three separate filters: a UAT-UK test for sixteen Oxford courses, written work capped at 2,000 words and due 10 November 2026, and published success rates that run from 5% to 42% depending on what you apply for. This page sets all three out, course by course, from the universities' own pages.

What actually decides an Oxbridge application, subject by subject?

The question every competing guide answers is "which test does my course need?". It is a fair question to ask third. Oxford receives over 23,000 applications for around 3,300 places every year and shortlists approximately 10,000 candidates, which means more than half the field is removed before a tutor has met anybody. What removes them is not a single test. It is a combination of the test, the written work submitted in November, and a subject-level competition ratio that varies far more between two courses at the same university than it does between the two universities.

Oxford publishes that variation on every course page as a three-year average, and almost nobody quotes it. Music interviews 92% of its applicants and admits 42% of them. Economics and Management interviews 18% and admits 5%. Those two courses take a similar number of students each year — an intake of 77 and 82 respectively — out of completely different-shaped fields. A candidate preparing for one and a candidate preparing for the other are not doing the same task, and they are not being filtered at the same point in the process.

Cambridge tells applicants it receives about six applications per place across all subjects, which corresponds to 22,513 applications and 3,669 acceptances in the 2025 cycle, a 16.3% success rate. That average is the least useful number on this page. Computer Science ran at 7.4% in the same cycle. The distance between the headline and the subject is the entire argument for preparing by course rather than by university, and it is why we treat admissions test preparation as one component of a plan rather than as the plan itself.

So this page is organised the way the process is organised. First, which Oxford courses require a UAT-UK test and when it is sat. Second, what Oxford's own shortlisting and success rates say about where each subject loses people. Third, the written work: how many pieces, how long, and by when. Then the same treatment for Cambridge, which works on a genuinely different model, and finally the interview stage, the international differences and what all of it implies for a preparation timetable.

Which Oxford courses need a UAT-UK test for 2027 entry?

For 2027 entry Oxford has moved its admissions testing onto the UAT-UK platform, and it publishes the list of courses requiring a test in full. Sixteen courses are on it. Three tests cover all sixteen: the ESAT for the science and engineering group, the TMUA for the mathematics and computing group, and TARA for the economics, politics, psychology and human sciences group. Medicine and Law sit outside that system, using the UCAT and the LNAT respectively.

The list rewards being read as a list, because the joint courses do not always follow the parent subject. Computer Science and Philosophy sits with the TMUA rather than with TARA. Physics and Philosophy takes the ESAT. History and Economics and History and Politics both take TARA, which means a History applicant may or may not sit a test at all depending entirely on which joint course they choose — straight History requires none. The same applies at the mathematics end, where three separate Mathematics combinations all route to the TMUA.

The timetable is fixed and it is early. Booking closes at 6pm UK time on 28 September 2026, before most Year 13 students have completed a full term of teaching. The tests are sat between 12 and 16 October 2026. Candidates receive their results through their UAT-UK account on 16 November 2026, which is after the written-work deadline and before interview invitations are issued. There is no late booking window, and missing 28 September is not a recoverable error.

If a course is not on the list, that is information rather than a reprieve. Geography appears nowhere on Oxford's 2027-entry test list, and Oxford's summary table shows it requires no written work either. For a Geography applicant the whole pre-interview assessment is the predicted grades, the personal statement and the reference, which changes what the autumn term of A-level study should be pointed at. Nothing in that says Geography is an easier admission; it says the evidence base is narrower, so each piece of it carries more.

What do Oxford's published shortlisting and success rates show?

Oxford states on each course page what percentage of applicants were interviewed, what percentage were successful, and the intake, averaged across three admissions cycles. These are the most actionable figures published anywhere in the Oxbridge process, and no competing page on this search result carries a single one of them.

Read the Interviewed column first, because it is the shortlisting gate and it is decided before any tutor has spoken to the candidate. It is settled on the test score, the predicted grades, the personal statement and, where required, the written work. Computer Science interviews 21% of its applicants for an intake of 55. Four applicants in five are removed on paper. Economics and Management is tighter still at 18%, and it is the hardest course on Oxford's published averages by both measures.

Then read the two columns together, because their relationship is the useful part. Music interviews 92% and admits 42%: almost every applicant reaches the interview, so the interview and the accompanying performance material carry effectively the whole decision. Mathematics interviews 32% and admits 9%, so roughly one interviewed Mathematics candidate in three receives an offer and the filtering is split across both stages. Nothing in these numbers says one subject is intrinsically harder than another. They say the subjects lose candidates in different places, which is a practical instruction about what to prepare and when to prepare it.

This is also why generic Oxbridge coaching underperforms so reliably. A Computer Science applicant who spends September and October on interview technique has invested in the stage they are least likely to reach. A Music applicant who spends the same weeks on test drills has prepared for a test that does not exist on their course. Both have worked hard and both have worked in the wrong place, and neither will discover it until November.

We use the same method across every course we cover in one-to-one subject tuition: find the stage that removes the most candidates for that specific course, put the work there first, and only then fill in the rest. The published rates make that decision for you, which is precisely why they are worth reading before anything else is planned.

What written work does Oxford want, and by when?

Written work is the most underestimated part of an Oxford application, largely because it is easy to describe and difficult to satisfy. One deadline covers the entire university: 10 November 2026. One cap covers every piece submitted: no single piece of submitted work may exceed 2,000 words. There is no extension mechanism and no course-by-course variation in either.

The word cap has a consequence that catches families late. Oxford states that extended essays for the International Baccalaureate, the Extended Project Qualification, or other pieces of work which exceed the 2,000 word limit are not acceptable as submitted written work. For a very large number of applicants, the longest, most researched and most heavily supervised piece of writing they own is therefore ineligible. If the EPQ was the plan, there is no plan, and the substitute has to be written in the same term as the test.

The load runs from nothing to three pieces, and Archaeology and Anthropology and Music carry the heaviest submission burden of any Oxford courses. At the other end, only two courses require both a UAT-UK test and written work: History and Economics and History and Politics. Everything else is one or the other, or neither. Knowing which of those three categories a course falls into determines the entire autumn workload, and it takes about a minute to check.

Oxford History adds an instruction that quietly disqualifies much of a typical A-level coursework folder. Its course page asks applicants not to send work that requires the assessor to read any source material, and to avoid source analyses or commentaries. A great deal of A-level History coursework is exactly that. The essay that satisfies Oxford is argument-driven and self-contained, no more than 2,000 words, and due on 10 November 2026 — which for most candidates means writing something new rather than retrieving something old.

English is the clearest case on this page. Oxford English Language and Literature has no admissions test for 2027 entry at all; the course page states that you do not need to take a written test as part of an application for this course. The whole pre-interview assessment is one analytical English Literature essay of no more than 2,000 words, submitted by 10 November 2026. A single artefact, chosen in September, carries a shortlisting decision that removes a third of the field. It is the easiest item on this page to start early and the one most often left latest.

How does Cambridge assess candidates differently?

Cambridge does not mirror Oxford, and assuming that it does is a common and costly mistake. Cambridge requires pre-registration for four named tests, and assesses everything else either through a College assessment or through no assessment at all. Which of those three applies to you is often a function of the College you pick rather than the course.

The LNAT is one of the four. Cambridge's admission tests table lists the National Test for Law against Law with advance registration required, exactly as Oxford does. The ESAT covers Chemical Engineering and Biotechnology, Engineering, Natural Sciences and Veterinary Medicine — and it is worth stopping on Veterinary Medicine, which uses the ESAT and not the UCAT. That catches applicants who reasonably assume that every course in the medical family shares a test. The TMUA covers Computer Science, Economics and Mathematics. Medicine uses the UCAT.

Two Colleges add a paper on top. Applicants to Peterhouse or Trinity for Computer Science also sit the Computer Sciences Aptitude Test. It is not an alternative to the TMUA and it does not replace anything; it is an additional assessment, and it exists because of the College named on the form rather than the course. That is a decision made in October with consequences in November, and it is one of the few places where College choice materially changes the workload.

For arts subjects the College dependency is close to total. English is assessed only at Gonville & Caius. History is assessed only at Hughes Hall and St Edmund's. Geography only at Hughes Hall, Philosophy only at Jesus and Trinity. So whether a Cambridge English applicant sits an assessment at all is settled by a single line on the UCAS form, and the honest answer to "what test does Cambridge English require?" is that for most applicants it requires none.

Where Cambridge does set a centrally dated College assessment, it publishes the specification in advance, which makes preparation concrete rather than speculative. The Linguistics assessment runs on Tuesday 17 November 2026: three parts of about 20 minutes each, 60 minutes in total, 30 marks per part and a 90-mark maximum. Architecture and Design share a single 30-minute assessment of graphic and spatial ability on Wednesday 18 November 2026, set by all Colleges. That second one tests a skill no A-level examines directly, which is exactly the argument for rehearsing it.

What do Cambridge's 2025-cycle success rates tell you?

Cambridge publishes a full subject-by-subject table for each admissions cycle. The 2025-cycle figures show a spread that the university's own headline average cannot represent, and they contain one row that changes how a Mathematics applicant should plan the whole of Year 13.

Computer Science at 7.4% is the sharpest end of the table. It is also the subject where the two universities independently agree: Oxford interviews only 21% of its Computer Science applicants and Cambridge admits 7.4% of its own. Two separate admissions processes producing the same shape is good evidence that the constraint is real rather than an artefact of one office's procedure. Economics at 10.0% is the next tightest, which lines up with Oxford's Economics and Management figures in the same direction.

Mathematics is the outlier and the most instructive row here. Cambridge made 555 Mathematics offers in the 2025 cycle and recorded 258 acceptances from 2,032 applications. That is the widest gap between offers and acceptances of any subject, and it is not students choosing to go elsewhere. The minimum Cambridge Mathematics offer is A*A*A plus grade 1 in STEP 2 and STEP 3, and STEP is sat in June, months after the interview. For Mathematics, the offer is not the finish line. The preparation window that decides the outcome runs into the summer of Year 13, long after every other applicant on this page has stopped.

Cambridge also publishes the figure that settles the "but they had straight A*s" conversation. In the 2025 cycle, 5,885 unsuccessful applicants went on to achieve the equivalent of A*AA or better on their best three A-levels, up from 5,617 the year before. At the same time, 94.2% of those who were accepted achieved A*AA or better. Read together, those two numbers say that top grades are close to necessary and nowhere near sufficient. Nothing in that data says the courses have become harder; it says the applicant pool is now uniformly excellent on grades, so grades have stopped being the thing that separates candidates.

One further figure changes how families should think about College choice. Of 4,893 offers made in the 2025 cycle, 3,940 came directly from the College applied to and 953 were made through the Winter Pool by a different College, with 4,375 applicants pooled in total. Roughly one offer in five therefore comes from somewhere other than the College named on the form. Choosing a College is worth doing thoughtfully, but it is not the lever most applicants believe it to be, and it should never displace subject preparation in the timetable.

What will interviews for 2027 entry actually look like?

Every Oxford interview for 2027 entry is online. There is no in-person option and no separate overseas pathway: shortlisted applicants are invited to online interviews in December 2026, which Oxford describes as academic conversations about your chosen subject, similar to a short tutorial and designed to explore how you think and engage with new ideas. That framing is worth taking literally, because it rules out the rehearsed-answer approach that most interview preparation defaults to.

Expect two interviews rather than one. Oxford states that it typically offers around 20,000 online interviews to approximately 10,000 shortlisted candidates. A candidate who has prepared for a single half-hour conversation and is then invited to two, potentially at different Colleges, has misjudged the stamina the day requires as well as the amount of material they need to be able to talk about.

Cambridge differs in both format and calendar. The main interview period runs from 7 to 18 December 2026, with Winter Pool interviews around mid to late January 2027. Format is decided College by College rather than centrally, and the two options genuinely diverge.

That table is not a detail. A candidate applying to Churchill, Emmanuel, King's or Selwyn will be travelling to Cambridge in December, with everything that implies for travel, timing and nerves. A candidate at Christ's, Downing, Fitzwilliam, Girton, Queens' or St John's will be sitting at a desk at home managing a camera, a connection and a screen. The rehearsal for those two experiences is not the same, and which one applies is knowable months in advance.

Decisions then land on different days. Oxford releases outcomes on 12 January 2027. Cambridge releases outcomes for candidates interviewed in the main December period on 27 January 2027, a fortnight later, with pooled candidates hearing after their January interviews. Any family holding other university offers should have both dates in the diary, because the gap between them is long enough to matter.

What changes for international applicants?

There is no separate international application route and no separate test route. There are, however, three differences that change the timetable, and two of them are frequently reported wrongly.

The first is a second deadline that has no Oxford equivalent. The UCAS deadline is 15 October 2026 at 6pm UK time and it applies identically to UK and international applicants. Cambridge then requires My Cambridge Application, a further form, by 22 October 2026 at 6pm UK time. It is not optional and it is not a formality: it is an extra application form you need to complete if you want to study at Cambridge, and missing it undermines an application already submitted through UCAS.

The second is a narrower test window for some candidates. Everyone else sits the UAT-UK tests across 12 to 16 October 2026, but Cambridge applicants in China, Hong Kong or Macau must take the ESAT on 12 or 13 October 2026 and the TMUA on 15 or 16 October 2026. A revision plan built around having the full week available does not survive contact with those dates, and for a candidate sitting both tests the compression is real.

The third is English language, where Oxford's current position differs from what most guides still print. There is now a single standard for all undergraduate courses: IELTS 7.5 overall with a minimum of 7.0 in each component. There is no lower band for so-called standard-level courses. Oxford recommends the IELTS Academic option and states that IELTS General, IELTS UKVI General and IELTS Life Skills are not suitable for admission, and that it cannot accept IELTS Online.

Two further points are routinely misreported. Oxford does not accept TOEFL tests taken from 21 January 2026, following changes introduced to the TOEFL iBT on that date which the university has under review; tests sat up to and including 20 January 2026 still count. And there is no blanket two-year shelf life on certificates — Oxford states that unless your English language certificate has an expiry date, the time when it was issued does not affect its validity. Families who assumed an older certificate had lapsed may find that it has not.

Medicine applicants at either university sit the UCAT, which has changed shape and no longer includes Abstract Reasoning. It now runs to four subtests, of which three feed a numerical total between 900 and 2700; Situational Judgement is reported separately.

Where does each subject actually lose its candidates?

Put the two halves of this page together — the requirements and the published rates — and a preparation plan more or less writes itself, one subject at a time. This is the part no competing page attempts, because it needs both sets of numbers in the same place.

Computer Science and Economics and Management are lost before the interview. Oxford interviews 21% and 18% of them respectively, and that decision is made on a TMUA or TARA score and a paper file. For those candidates the autumn of Year 13 belongs to the test, and part of the preparation was already done a year earlier: 96% of A-level students offered places for Oxford Computer Science courses between 2022 and 2025 took Further Mathematics. That is not stated as a requirement, but it is what the successful cohort looks like, and it is a decision made when options are chosen rather than when applications are written.

English and History are lost on a single essay. No test, one piece, a hard 2,000-word cap, a deadline of 10 November 2026, and for History an explicit instruction to avoid source analysis. The work is choosing the right essay in September and rewriting it properly through October. There is no second submission and no resit, and no amount of interview practice compensates for a weak piece of writing that prevented the interview from happening.

Cambridge Mathematics is lost after the offer. 555 offers, 258 acceptances, and a condition of grade 1 in STEP 2 and STEP 3 sat the following June. A programme that stops at the December interview has covered perhaps two-thirds of what the offer actually asks for, and the final third is the part with the highest failure rate.

Music, and courses shaped like it, are decided in the room. When 92% of applicants are interviewed, the shortlisting stage is barely a filter and the interview plus the submitted material carries almost the whole decision. The scarce resource there is not access to the interview; it is what happens once you are in it.

None of this needs a different tutor at every stage. It needs somebody to identify which stage will remove the candidate and to start there. Our sixth-form and university entrance support begins from the published figures for the specific course rather than from a general Oxbridge template, and the first conversation is usually about which of these four patterns the course falls into. If you would like that mapped out for your child's course, book a consultation and we will work through it with you.
