Best A-Level combinations for Oxbridge: Your course-by-course guide

If you've typed "best A-Level combinations for Oxbridge" into Google, the honest answer is that there isn't one.

The subjects a Cambridge Medicine applicant needs have almost nothing in common with the subjects a Cambridge English applicant needs. Oxford Medicine wants Chemistry, Biology and Maths. Cambridge English wants English Literature, History and a Modern Language. Neither combination opens the other door, and if you pick one hoping it keeps the other open, you'll find out at exactly the wrong moment.

Oxford and Cambridge aren't the same place either. They use different course names (Oxford's Law is "Jurisprudence"; Cambridge Psychology is "PBS", Oxford's is "Experimental Psychology"), different admissions tests, different interview formats, and sometimes substantially different course content. Cambridge Natural Sciences is a joint-honours structure; Oxford splits those subjects into separate courses. And in a typical UCAS cycle you can only apply to one of the two, not both.

So this guide goes course by course. For each one, we'll say which combination keeps it open, flag the admissions test that applies at the moment (with the heavy caveat that tests have been churning since 2023), and clear up the misconceptions that come up most. Entry requirements change year to year, so always check the current offer and tests on the university's own course page before you commit to anything.

Standard Oxford offers run from AAA (Law, PPE, History, English, Classics) up to AAA for Mathematics and Engineering Science, with Computer Science, Medicine and Economics and Management asking for AAA. Cambridge in a typical year sits around AAA for sciences and maths and AAA for arts. Specific grades shift by course and year, so check each course page. Our A-Level grades explained guide walks through how boundaries get set and what each grade represents.

For each course below, we've listed the combination that keeps it open, the admissions test that applies at the moment, and the usual "verify this year's test" caveat.

Chemistry is required at both. Both also want at least one of Biology, Physics or Maths; Biology is recommended at Cambridge, Oxford Medicine lists Biology as "Not applicable", and some Cambridge colleges set extra requirements on top. The third subject is flexible, with Maths or Physics the most common pick.

The test situation is the one most people get burned on. UCAT is required at Oxford. Cambridge historically used the BMAT, which retired after 2023, so Cambridge Medicine has shifted to the UCAT in recent years. Verify the current test on the course page before you book anything.

Neither Oxford's Jurisprudence (that's what Oxford calls Law) nor Cambridge Law requires a specific subject. In practice, essay subjects like History, English Literature and Politics are an advantage at the top end. The LNAT is required at both now (Cambridge replaced its own Cambridge Law Test with the LNAT a couple of years back); for 2027 entry it has to be sat by 15 October 2026.

Maths is essential, which won't surprise anyone. Further Maths is effectively required at Cambridge and recommended at Oxford. Both now use the TMUA for 2027 entry (Oxford has dropped the MAT), and Cambridge offers are also conditional on STEP.

Cambridge Natural Sciences wants A-Level Maths plus two of Biology, Chemistry, Physics or Further Maths. Three sciences strengthens the offer. Oxford doesn't offer NatSci at all; it splits the same subject areas into separate Biology, Chemistry, Physics and Biochemistry courses with their own requirements. ESAT is typically required at Cambridge NatSci (it replaced the retired NSAA). Verify the current test.

Maths plus Physics required at both. Further Maths is strongly encouraged at Cambridge; at Oxford it's listed as helpful but "not required for admission". The ENGAA has retired, so Cambridge Engineering now uses ESAT. Oxford Engineering Science also uses the ESAT (the PAT has been scrapped for 2027 entry). Verify the current test.

Maths is required at both. Further Maths is strongly recommended, and effectively required at Cambridge. The TMUA is now required at both Cambridge and Oxford (Oxford has dropped the MAT), and a few Cambridge colleges also set the CSAT at interview. Verify the current test.

Maths is required at both. Several Cambridge colleges also require Further Maths (Christ's, Churchill, Corpus Christi, Magdalene, St John's and Sidney Sussex), so your college choice matters here. Oxford E&M requires the TARA (Test of Academic Reasoning for Admissions), which replaced the TSA for 2027 entry. Cambridge Economics requires the TMUA. Verify the current test.

Oxford's PPE doesn't list a specific required subject; it recommends Maths and lists History as helpful. Cambridge's HSPS is the nearest equivalent on the Cambridge side. The TARA is required for PPE for 2027 entry (it replaced the TSA).

English Literature (or English Language and Literature) A-Level is required at both (Cambridge English, Oxford English Language and Literature). The ELAT (the Oxford English Literature Admissions Test) retired after 2023. Verify the current test at each university.

History A-Level is required at Cambridge. Oxford History no longer has an admissions test (the HAT has been discontinued), but you submit written work instead. Cambridge History uses its own written assessment.

Latin or Greek is required for Cambridge's three-year Classics course; Oxford doesn't require either, though both are listed as helpful. Cambridge offers a four-year Classics course (Q801) for applicants without A-Level Latin, and Oxford's single four-year Classics course (Q800) accepts applicants with or without Latin or Greek.

A-Level in the chosen language is typically required. There's some flexibility for ab initio languages (ones you haven't studied before), so if you've got a grandparent who speaks Russian and you want to take it up at university, the door isn't closed.

Oxford Experimental Psychology doesn't require a specific subject (a science, including Psychology, or Maths is recommended). Cambridge PBS requires at least one of Maths, Biology, Chemistry, Computer Science or Physics.

These two courses look similar from a distance and aren't. Cambridge PBS is substantially broader, pulling in Sociology, Social Anthropology and other behavioural sciences. Oxford Experimental Psychology is mostly scientific and cognitive psychology. Treat them as different courses, because they are.

University admissions pages are the authoritative source for subject guidance now. The Russell Group scrapped its old "facilitating subjects" list in 2019 and replaced it with its Informed Choices website, which gives general guidance only. There's no central cross-university rulebook any more. For Oxbridge, both universities publish their guidance openly on each course page, so that's where to go.

Since the right combination is course-specific, these four stacks are grouped by broad career goal rather than by university. Each one keeps every Oxbridge course relevant to that goal open.

Oxbridge also publishes contextual offers for some courses, with lower grade requirements for applicants from widening-participation backgrounds. These vary by course and aren't available for every student, so check each course page for the current wording if you think you might be eligible.

Don't base your subject choice on the possibility of a contextual offer though. Pick the strongest combination you can realistically achieve, and treat a contextual offer as a bonus if it applies. Our full list of A-Level subjects covers what's available beyond these four stacks, including whether a fourth A-Level actually strengthens a competitive application.

Oxbridge leans harder on admissions tests than almost any other UK university system. On top of A-Level grades, you'll typically sit a course-specific test in autumn of Year 13 and, if shortlisted, attend an interview in December.

The lore was that if you knew the test for your course, you were sorted. That stopped being true around 2023, and it's been changing ever since. BMAT (Cambridge Medicine, some dental schools) retired. ENGAA (Cambridge Engineering) retired. ELAT (Oxford English) retired. The ESAT replaced the NSAA for Cambridge science and engineering courses. And for 2027 entry Oxford has replaced the MAT, PAT, TSA and its other in-house tests with the TMUA, ESAT and TARA.

So the specific test you prepare for depends on the university AND the course AND the year. There's no shortcut: check each course page for the current test and plan prep around it. Any guide written before 2024 (including the one your sixth form may have given you) is probably wrong on this.

As for what's on them: some tests are maths-based (STEP, TMUA, ESAT), some are reasoning-based (the TARA, parts of the LNAT, UCAT), some are writing-based (the TARA's writing task, the LNAT essay, Cambridge's college-set written assessments) and some are mixed. Your A-Level combination doesn't directly dictate the test content, but students whose subjects line up with the test tend to find it more approachable.

Once you've shortlisted the course you want and the combination that supports it, our guide to how UCAS points work explains the tariff system used by most UK universities, though Oxbridge makes offers in specific grades rather than points.

The best thing to do is to read the current course page on both Oxford's and Cambridge's websites, even if you're only applying to one. Each university publishes its typical offers, admissions tests and subject guidance openly, and the wording often tells you things guides like this one don't.

Book an open day at both universities during Year 12 if you can. Course-specific sessions often include admissions tutors answering direct questions about subject choice, admissions tests and the differences between Oxford's and Cambridge's versions of the same subject. That's far more current than any article, this one included. And ask older students who've already been through it, not the open evening pitch, because what they say about the workload and the interview is usually more honest.

Start admissions test prep in the Year 12 summer at the latest. TMUA, ESAT, TARA, STEP and LNAT all reward serious practice, and the questions are harder than anything in A-Level. Our guide to A-Level Maths vs Further Maths explains why Further Maths pays off for competitive STEM-adjacent applications, and our complete guide to AQA A-Level History covers what humanities A-Level reading looks like at the kind of depth Oxbridge interviews expect.

For interview prep, read widely around your subject from early Year 12. Oxbridge interviews are built around how you think, not what you've memorised. Students who've been reading around their subject for a year tend to outperform students who crammed in the two months before interview.

One last thing: don't trust any single guide, this one included. The authoritative source is each university's own course page in the current year. Admissions rules change, tests retire and get replaced, so read the current page before any decision that matters.
