If you're picking A-Levels and you want to study psychology at uni, the honest answer is there isn't one right combination. The one that gets you into UCL isn't the one you need for a post-92, and the one you need for Cambridge PBS is different again.
Psychology has one of the widest spreads of entry requirements of any UK degree. At one end, Cambridge PBS (Psychological and Behavioural Sciences) and Oxford Experimental Psychology are hunting the same students as medicine. At the other end, loads of post-92s will take any three A-Levels at the specified grades. So what you pick really does depend on where you're aiming.
What this guide actually does is map the spread, explain what each tier asks for, and flag the thing most students and parents don't realise matters more than the university's ranking: BPS (British Psychological Society) accreditation. That's the bit that decides whether you can train as a professional psychologist after your degree, and it's the easiest thing to miss. Entry requirements shift year to year, so verify the current offer on the university's course page before you commit.
This article was last checked against official university admissions pages and the BPS accredited courses list on 14 October 2026 for 2027 entry. Admissions tests, accreditation status and offer wording change often, so cross-check the BPS accredited courses database and each named university's current course page before you rely on any specific detail.
What universities actually require (by tier)
Roughly ordered from most selective down.
At the top end, you've got Oxford Experimental Psychology and Cambridge PBS, which sit above everything else with their own course-specific tests and interviews. The top Russell Group BSc tier (UCL, KCL, Bath, Nottingham, Exeter, York) wants a strong offer including a science or maths. Some of them, including UCL and Durham, will count Psychology A-Level as the science. Bath Psychology doesn't require any specific subject but asks for a mix of numerical and essay-based ones, and treats Psychology as counting for either.
Below that is the mid Russell Group (Birmingham, Bristol, Durham, Manchester, Southampton, Cardiff, Edinburgh, Glasgow). A strong offer, with a science or maths usually preferred rather than required. Rules vary by course and change year to year, so check each page.
Most post-92 universities will take any three A-Levels at the specified grade. No subject requirement in a typical year.
The sharp end is where the detail matters. UCL Psychology BSc asks for subjects from a list that includes biology, chemistry, maths, physics and psychology, so Psychology A-Level does count. Cambridge PBS now wants at least one of maths, biology, chemistry, computer science or physics at A-Level. Oxford Experimental Psychology has no formally required subjects but values sciences or maths. The wording on all of these shifts, so verify on each course page before you anchor on anything.
Grade requirements vary by course and year too. The BPS accredited courses database is the right starting point for shortlisting.
One thing worth knowing on where the "rules" come from. The Russell Group used to publish a central list of "facilitating subjects" that worked as a cheat sheet across most of its universities. They scrapped it in 2019 and replaced it with the Informed Choices site, which only gives general guidance. There isn't really a cross-university rulebook any more, which is why checking each university's own course page matters so much.
The thing most students and parents miss is that BPS accreditation matters more than university ranking for employability as a professional psychologist. A BPS-accredited BSc Psychology from a post-92 university opens the chartered-psychologist route. A non-accredited course from a Russell Group university does not. If you plan to practise clinical, educational, forensic or counselling psychology, check the BPS accredited courses list before you shortlist.
A-Level combinations ranked
The four combinations below run from "opens every BSc Psychology including Oxbridge" through to combinations that work fine at post-92s but close the top Russell Group BSc off. The best thing to do is to match the combination to the tier you're actually aiming at, not to a vague ambition.
Biology + Psychology + Maths (strong, opens every BSc incl. Oxbridge)
The textbook top-end stack. Biology covers the science requirement anywhere that has one. Maths covers the statistics side, and every BSc Psychology has substantial stats modules whether students realise that going in or not. Psychology A-Level gives you a head start on the first-year content. Keeps every tier open.
Biology + Psychology + an essay subject (strong alternative, English Lit or Sociology)
Also opens every BSc Psychology. The essay subject strengthens the critical-writing side, which matters at university because psychology essays are longer and more argumentative than most Year 12s expect. Less quantitative than the first option, so if you're drawn to cognitive or computational psychology you might prefer the maths version.
Psychology + Sociology + Maths (mid, keeps Bath and UCL open)
No traditional lab science, but still a strong combination. Bath Psychology doesn't require specific subjects and counts Psychology as both numerical and essay-based, so this keeps Bath open. UCL Psychology asks for subjects from biology, chemistry, maths, physics and psychology, so Psychology + Maths satisfies them too. Fine across much of the mid Russell Group and almost all post-92s. Verify the current wording at each target.
Biology + Chemistry + Psychology (pivot-friendly, Psych + Neuroscience + Medicine Plan B)
Opens every Psychology BSc including the science-heavy ones, and keeps neuroscience, biomedical science and medicine on the table as backup plans. Academically the hardest of the four, but it's the one that keeps the widest range of brain-and-behaviour destinations open if you're not sure yet.
Combinations that quietly close the top Russell Group BSc off are worth flagging too. Psychology + Sociology + Media Studies is a common pick with no science, which rules out UCL and Cambridge PBS (which now wants a science or maths) and leaves you weaker at Bath and Oxford. Three humanities with no science or maths is fine at post-92s but closes most of the top Russell Group. Three sciences without Psychology isn't disqualifying anywhere, and the top Russell Group is usually fine, you just lose the head start on first-year content.
Two edge cases people ask about a lot: Psychology A-Level does count towards UCL's subject requirement, and Bath doesn't require any specific subject at all. Verify both at each university before relying on them.

The admissions test situation
Most UK Psychology courses don't need you to sit a separate admissions test. The exceptions are at Oxbridge. Oxford Experimental Psychology and Cambridge PBS have historically used reasoning tests and college-set written assessments at the admissions stage, and both interview the applicants they shortlist. The specific test used has changed in recent cycles, so verify the current requirement on each course page.
Admissions tests across top universities have been in flux since 2023 anyway. Several (BMAT, ENGAA and ELAT) were retired, and others got reshuffled. If you're applying to Oxbridge Psychology, double-check the current test requirement on each course page before you spend time preparing for the wrong one.
For anywhere else, your A-Level grades, personal statement and interview (if you get one) are what the admissions team is actually using. UCAT isn't a Psychology thing. It's for medicine and dentistry.
Common misconceptions, cleared up
What to do next
Once you've got a combination you're happy with, there are a few things worth doing before you commit.
Check the BPS accredited courses list for every university you're seriously considering. If you want to work as a professional psychologist, this is the most important check, and it's the one people skip most. Plenty of post-92 courses are accredited, and some Russell Group departments run both accredited and non-accredited routes under the same umbrella, so always confirm which one you'd actually be on.
Then check the current course page for every target. Entry requirements, admissions tests and whether Psychology counts as a science all shift year to year, so your Year 12 self needs to go to the authoritative source rather than trusting any guide (including this one).
Book open days at two or three targets during Year 12. Psychology admissions tutors are usually happy to answer subject-choice questions directly at open-day sessions, and the information you get is more current than any article's. If you can, ask the current students too, not just the staff doing the pitch.
For a feel of what Psychology A-Level actually involves, our complete guide to AQA A-Level Psychology covers the content and skills. For the biology side (useful whether you're taking Biology A-Level or just want to understand how it fits), our complete guide to AQA A-Level Biology walks through the specification.
One last thing. Psychology is one of the most popular UK degrees, and it's also one of the most variable in terms of what the degree actually trains you to do. BPS accreditation plus a BSc plus strong research methods training is the standard route into professional psychology. BA Psychology without accreditation is a legitimate humanities degree, but it doesn't open the professional route on its own. Pick the path that matches the career you actually want, not the one that sounds impressive now.
