A Level subject combinations for top universities

How A Level combinations are used by universities

UK universities use the A Level combination in three ways. First, as a hard gate: every degree publishes specific subject requirements (chemistry and biology for medicine, mathematics and physics for engineering, mathematics for economics at most universities). A candidate without the required subject is filtered out at the first sift, regardless of grade prediction. Second, as a soft signal: a candidate with three traditional academic subjects is read more favourably than a candidate with three vocational or applied subjects at the same grade level. Third, as a course fit signal: a candidate whose subjects align tightly with the course they have applied to is treated as more serious about the choice than a candidate whose subjects look like a generic strong portfolio.

The combination matters more than the average pupil and parent realise. Two candidates with three A grades can have very different chances of admission to the same course at the same university based on subject choice alone. The pupil targeting computer science at Imperial with mathematics, further mathematics and physics is a competitive applicant; the pupil targeting the same course with business studies, geography and biology has effectively ruled themselves out at sift even before the grade is known. The combination is set in stone at the end of Year 11 and cannot be changed without restarting. The decision needs careful thought in Year 10 and early Year 11.

Facilitating subjects and the Russell Group

The Russell Group published an Informed Choices guide for over a decade that listed eight "facilitating" subjects, defined as subjects most commonly required for Russell Group degrees. The list covered mathematics, further mathematics, English literature, physics, biology, chemistry, geography and history, plus modern and classical languages. The advice was that two facilitating subjects in the A Level combination kept the widest range of Russell Group degrees open, three was even better for keeping options open across science and humanities, and a combination with no facilitating subjects narrowed the candidate's degree options sharply at Russell Group level.

The Russell Group withdrew the formal "facilitating" label in 2019, partly because it had become misunderstood as a mandatory list rather than guidance. The underlying principle still holds at every Russell Group university, however. The traditional academic subjects open more degrees and signal more academic seriousness than the applied or vocational subjects. A pupil with mathematics, chemistry and physics has more degrees open than a pupil with media studies, business studies and law, both at A grade. The Russell Group's current Informed Choices microsite at informedchoices.ac.uk lets a pupil search degrees by subject and is the canonical source for current requirements. Our piece on A Level reform impact 2026 covers recent UK changes to the qualification structure.

What Oxbridge wants

Oxford and Cambridge admission is based on academic potential demonstrated through grades, subject choice, admissions tests, written work where required, and the interview. The A Level combination matters at Oxbridge in the same way as at the wider Russell Group but the bar is higher. Oxbridge expects three academic subjects (in some courses four, including further mathematics) at the predicted A* level. The combination should match the course tightly: mathematics, further mathematics and physics for engineering; chemistry, biology and one of mathematics or physics for medicine; mathematics and two others including economics for economics and management; English literature, history and a language for English; classical languages for classics; and so on. Oxbridge does not interview candidates whose A Level combination signals weak course fit, regardless of predicted grades.

Further mathematics is the single highest leverage subject for Oxbridge in mathematics, physics, engineering, computer science and economics. Strong Oxbridge applicants in these areas almost universally take further mathematics. The strongest mathematics applicants take mathematics, further mathematics, physics and one more, a portfolio of four A Levels rather than three. The college and admissions tutor signal further mathematics as essential rather than helpful for the strongest mathematical sciences. Our piece on Cambridge IGCSE versus Edexcel covers the qualification before A Level.

Medicine and dentistry

Medicine at the standard UK universities requires chemistry and at least one of biology, mathematics or physics, with most universities requiring both chemistry and biology. The third subject is more flexible: another science (physics or mathematics) is the most common third choice and the safest, but humanities can work where the predicted grades are strong. Cambridge, Oxford and Imperial expect chemistry, biology and one of mathematics or physics. Cambridge can interview with chemistry and any two of biology, mathematics or physics. Most other Russell Group medical schools (Edinburgh, UCL, King's, Manchester, Newcastle, Bristol, Sheffield, Cardiff) require chemistry and biology with one other subject of the candidate's choice.

Dentistry follows essentially the same rules as medicine. Veterinary medicine requires chemistry and biology with strong grades; some courses also require physics or mathematics as the third subject. The grade requirement is universally A*AA or AAA from the strongest applicants and AAB to ABB at the more accessible universities. The UCAT and BMAT admissions tests sit alongside the A Level combination at most medical and dental schools. The combination question for medicine and dentistry is more constrained than for any other course family; pupils intending medicine should commit to chemistry and biology in Year 11 without flexibility.

Engineering and computer science

Engineering at the top UK universities requires mathematics and physics, with the third subject typically further mathematics or chemistry. Cambridge engineering, Imperial engineering and Oxford engineering science all expect mathematics, further mathematics and physics from the strongest candidates. Some courses (chemical engineering, biomedical engineering) substitute chemistry for further mathematics or physics depending on the course. The grade requirement is A*A*A to A*AA at the strongest universities and AAA to AAB at the wider Russell Group.

Computer science requires mathematics at every Russell Group university and most increasingly require further mathematics. Cambridge computer science, Imperial computing and Oxford computer science expect mathematics and further mathematics, with the third subject typically physics or further mathematics modules. Computer science as an A Level subject does help signal interest but is rarely required and is not usually treated as a substitute for further mathematics. The strongest UK computer science applicants combine mathematics, further mathematics and physics. The combination of mathematics, computer science and a non STEM subject is materially weaker at top university entry. Our piece on which curriculum is best for STEM covers the wider STEM pathway.

Natural sciences and biomedical sciences

Natural sciences at Cambridge requires three science or mathematics subjects from a broad list: biology, chemistry, physics, mathematics, further mathematics. The strongest applicants take all three sciences plus mathematics (a four A Level portfolio). Three of the four sciences is the standard minimum. Natural sciences at UCL and Durham, biomedical sciences at most universities, and biochemistry follow similar patterns: chemistry and biology core, with mathematics or physics as the third. The grade requirement is A*AA to AAA at the strongest universities.

Economics, PPE and business

Economics at Cambridge, LSE, Warwick, UCL, Oxford PPE and Oxford economics and management requires mathematics as a hard gate, with most also requiring or strongly preferring further mathematics. The second and third subjects are more flexible: economics A Level is helpful but not required, history is well regarded, languages signal academic breadth, and further mathematics is the strongest possible second subject for the most quantitative degrees (LSE econ, Cambridge econ, Warwick MORSE). PPE at Oxford and the wider PPE courses (UCL, York, Manchester) require mathematics and benefit from history or economics as the second subject.

Business and management at the Russell Group is less rigid on subject combination than economics. Mathematics is helpful but not required at most universities. Business studies A Level is widely available but is not treated as strongly as economics A Level. The strongest business applications combine mathematics, economics and one other strong academic subject (history, geography, a science, or a language). Combinations of three vocational subjects (business studies, applied business, applied ICT) are read less favourably even at AAB grade. The IB versus British curriculum piece covers the broader pre university qualification choice for these subject areas.

Law

Law has no required subject at any UK university. The Russell Group accepts any three A Level subjects at the appropriate grade level. The strongest law applicants combine traditional academic subjects: English literature, history, a language, mathematics, philosophy, economics. Law A Level itself is widely available but is not treated as more weighty than the broader essay subjects; some admissions tutors prefer candidates without law A Level on the grounds that the candidate has not yet been pre exposed to legal thinking. The grade requirement is A*AA to AAA at Oxbridge, UCL and LSE, and AAA to AAB at the wider Russell Group law programmes.

History, English and humanities

History at Oxford, Cambridge, UCL, Durham and the wider Russell Group requires history A Level at most universities. The second and third subjects are most often English literature, a language, philosophy, economics, geography or another humanities. The combination of history with two languages is particularly strong for Oxbridge historians. English literature at the top universities benefits from a second essay heavy subject (history, philosophy, religious studies, a language). The combination of English literature with two sciences is unusual but not penalised where the grades are strong.

Geography is a hybrid subject that can support either humanities or science applications. Geography combined with history and a language reads as a humanities portfolio. Geography combined with biology and mathematics reads as a science portfolio. Geography is treated as a facilitating subject at every Russell Group university.

Modern languages and area studies

Modern languages at the top universities require the language A Level for the spoken language papers. The strongest candidates combine a modern language with English literature, history or a second language. Two languages plus a third academic subject is the highest level Oxbridge languages portfolio. Latin and Greek at A Level are facilitating subjects for classics at Oxford and Cambridge, alongside ancient history and English literature. Area studies (Russian, Arabic, Chinese, Japanese, Korean) at the top universities take candidates with the language A Level and a related academic subject, although some take strong applicants without prior language study where the wider portfolio is convincing.

Subjects to avoid for top entry

For Oxbridge and the strongest Russell Group degrees, certain A Levels signal weaker academic preparation regardless of the grade earned: applied ICT, business studies as the only economics related subject, media studies, photography, dance, drama, design technology in some courses, and the strongly applied or vocational subjects. The Oxbridge admissions tutor guidance has historically named these subjects on a "not preferred" list at some colleges. The wider Russell Group has been less explicit but the same effect operates at sift.

This does not mean the subjects are bad in absolute terms. They are useful for some career paths and some non Russell Group universities. The point is that they should not appear as more than one of three A Levels for a candidate targeting Oxbridge or the strongest Russell Group degrees. A candidate with English literature, history and media studies is broadly competitive at the Russell Group; a candidate with three applied or vocational subjects at the same grade is materially weaker.

The fourth A Level question

Whether to take three A Levels or four is one of the most asked questions in Year 11. The honest answer is that three at A* level beats four at A level for almost every university. The fourth A Level adds workload that often pulls down the grades on the three core subjects. Universities make offers in terms of three subjects (A*AA, AAA, AAB) and rarely require four. The exceptions are mathematics intensive degrees at Cambridge, Imperial and the strongest LSE programmes, where further mathematics as the fourth A Level adds genuine signal value, and the strongest applicants do take four A Levels including further mathematics.

For the wider Russell Group, three A Levels at the predicted grade level is the standard advice. A pupil considering a fourth A Level should ask: does the fourth subject open courses I would otherwise be excluded from, and can I sustain the predicted grades on three at the same time. If the answer to either is no, three is the right number. If both are yes, four is worth considering. Most international British schools allow either pattern; some default to four for the top set and three for the others.
