Choosing A levels for medicine can feel surprisingly complicated. One student may be told that they must take Biology, Chemistry aieces of advice contain some truth, but neither tells the whole story.

Medical schools set their own subject requirements. Some insist on both Biology and Chemistry. Others require Chemistry plus another science, while a growing number accept Biology or Chemistry alongside a second scientific subject.

The safest choices depend on which medical schools a student may eventually want to apply to. This article reflects published information available on 1 August 2026 for students considering 2027 entry, but requirements can change. Every applicant must check the medical school’s own website before choosing subjects or applying. The Medical Schools Council also provides a useful entry-requirements database covering UK medical courses. edical schools, not subject myths

Students are often told that there is one correct A-level combination for medicine. There is not.

For example:

• UCL requires both Biology and Chemistry.
• Oxford requires Chemistry and at least one of Biology, Physics, Mathematics or Further Mathematics.
• Manchester requires Biology or Chemistry plus another accepted science.
• Sheffield requires Chemistry or Biology plus a second science.
• Cambridge requires Chemistry and additional science or mathematics subjects, with precise requirements varying between colleges.

These differences matter. A combination accepted by one medical school may leave a student ineligible for another. A levels, students should identify at least eight to ten medical schools they might realistically consider and record their subject requirements.

2. Biology, Chemistry and Mathematics remains the safest traditional combination

For a student who enjoys all three subjects and is likely to achieve high grades, Biology, Chemistry and Mathematics remains one of the safest combinations.

It satisfies the subject requirements of a very wide range of medical schools and provides useful preparation for scientific study.

However, this does not mean that every future doctor must study Mathematics at A level. Nor does it mean that a student should choose Mathematics if it is likely to reduce their overall grades.

Medicine offers are usually based on three A levels. Three excellent grades are normally more useful than choosing a supposedly impressive combination and missing the required grades.

3. Chemistry keeps the greatest number of options open

Chemistry is still the most important individual A level for maximising medical-school choice.

Oxford requires Chemistry. Cambridge requires it. Many other courses either require Chemistry or expect it alongside Biology.

Chemistry develops knowledge of bonding, energetics, equilibrium, organic reactions and molecular structure. These ideas support later learning in areas such as biochemistry, pharmacology and physiology.

It is possible to study medicine without A-level Chemistry at some universities, but a student who leaves it out must accept that their list of possible medical schools will become smaller. he other safest choice

Biology is compulsory at medical schools such as UCL and Nottingham, while many others accept it as one of the required sciences.

It also gives students useful preparation for topics including:

• cells and tissues;
• genetics;
• immunity;
• respiration;
• homeostasis;
• the nervous system;
• circulation;
• disease;
• experimental work.

Oxford does not insist on A-level Biology if the applicant has Chemistry and another approved science or Mathematics subject. Nevertheless, Biology and Chemistry together provide access to more medical schools than either subject alone. eneral recommendation is Biology and Chemistry plus a strong third subject

For most students who are reasonably certain that they want to study medicine, the clearest advice is:

Choose Biology and Chemistry, followed by the academic subject in which you are most likely to achieve a high grade.

That third subject might be:

• Mathematics;
• Physics;
• Psychology;
• English Literature;
• History;
• Geography;
• a modern language;
• Economics;
• Computer Science.

The third subject does not always need to be another science. UCL, for example, requires Biology and Chemistry but allows the student to choose the third subject, apart from qualifications it specifically excludes. is useful, but it is not compulsory for most medical schools

Mathematics can be an excellent choice for a future medical student. It supports:

• interpreting data;
• rearranging equations;
• understanding rates and proportions;
• analysing graphs;
• studying probability and statistics;
• working confidently with scientific calculations.

It can also keep alternative degree options open in areas such as chemistry, engineering, economics, computing and some natural sciences.

However, most medical schools do not require A-level Mathematics. A student should not select it simply because they believe medical schools will automatically prefer it.

A grade A or A* in another accepted subject is generally more useful than a lower grade in Mathematics chosen only because it appears traditional.

7. Physics is a valid and valuable third science

Physics is accepted as an additional science by many medical schools, including Oxford.

It can be particularly helpful for students interested in:

• medical imaging;
• radiotherapy;
• biomechanics;
• pressure and fluid flow;
• electricity and the nervous system;
• ultrasound;
• radiation;
• medical technology.

A combination of Biology, Chemistry and Physics can therefore be an excellent preparation for medicine.

Students should still choose carefully. Physics is mathematically demanding, and taking three laboratory sciences creates a substantial practical and written workload. It should be chosen because the student enjoys it and can succeed in it, not simply because three sciences appear impressive. s accepted by some medical schools, but not all

Psychology can be highly relevant to medicine. Doctors need to understand behaviour, memory, mental health, communication, development and the ways patients respond to illness.

Some medical schools count Psychology as an accepted second science. Manchester, for example, includes Psychology within its list of accepted subjects alongside Biology, Chemistry, Physics and Mathematics. y is not accepted as the required additional science everywhere. Oxford’s approved list alongside Chemistry is Biology, Physics, Mathematics or Further Mathematics.

A student considering Psychology should therefore check individual requirements carefully rather than assuming every medical school will treat it as a laboratory science.

9. A humanities subject can make an excellent third choice

Medicine is not only about scientific knowledge. Doctors also need to:

• read critically;
• communicate clearly;
• understand different perspectives;
• construct evidence-based arguments;
• recognise ethical questions;
• write accurately;
• make decisions when evidence is incomplete.

Subjects such as English Literature, History, Geography, Philosophy, Religious Studies and modern languages can help to develop these abilities.

A student taking Biology, Chemistry and History is not automatically at a disadvantage compared with one taking Biology, Chemistry and Mathematics.

Where the required sciences have already been covered, the third subject should usually be one that the student enjoys, can discuss enthusiastically and has a strong chance of achieving at A or A*.

10. Do not take four A levels simply to impress medical schools

Taking four A levels does not normally produce an automatic admissions advantage.

Oxford states that its standard medicine offer is based on three A levels and that applicants offering four subjects should not receive a four-grade offer. Manchester similarly explains that offers are normally based on three full A levels, even when applicants are studying more. ay be appropriate when:

• the student genuinely enjoys all four subjects;
• the school normally begins Year 12 with four;
• the student wants time before deciding which subject to drop;
• Further Mathematics is being taken alongside Mathematics;
• the workload will not harm grades, UCAT preparation or wellbeing.

It should not be taken because a student believes medical schools expect four A levels.

11. Be careful with Mathematics and Further Mathematics

Mathematics and Further Mathematics can be a strong combination, but some medical schools will not count them as two sufficiently distinct subjects.

Sheffield does not accept Further Mathematics when determining whether an applicant has met its normal A-level academic threshold. Other medical schools may count only one of Mathematics and Further Mathematics within their required three subjects. ing Chemistry, Mathematics and Further Mathematics could therefore find that Biology is missing and that some universities do not treat the two mathematics qualifications separately.

For maximum flexibility, Chemistry, Biology and Mathematics is usually safer than Chemistry, Mathematics and Further Mathematics.

12. Human Biology is not always treated exactly like Biology

Some universities accept Human Biology as an alternative to Biology. Others place restrictions on combinations such as Biology and Human Biology because the content overlaps.

The same problem can arise with combinations involving Mathematics and Further Mathematics.

Students should not assume that two qualifications with different titles will automatically count as two separate sciences. They must check:

• whether Human Biology is accepted;
• whether Biology and Human Biology can both form part of the offer;
• whether Mathematics and Further Mathematics are counted separately;
• whether Psychology, Statistics or Computer Science is classed as a science.

Medical schools use different definitions of an acceptable science subject.

13. Check how vocational qualifications are treated

Students taking BTECs, T Levels or mixed A-level and vocational programmes must investigate entry requirements particularly carefully.

Some medical schools accept certain Applied Science qualifications alongside specified A levels. Others do not accept BTECs or T Levels for standard-entry medicine.

Oxford, for example, lists particular BTEC Applied Science combinations but still requires specific chemistry content or additional science A levels. Sheffield’s standard medicine course does not accept the BTEC Extended Diploma or T Level as direct replacements for its A-level requirements. ce course can be demanding and valuable, but this does not guarantee that it meets the entry requirements for medicine.

Students should obtain written confirmation directly from each medical school before beginning an unusual qualification combination.

14. Pass the science practical endorsement

Where an A-level science includes a practical endorsement, medical schools commonly expect applicants to pass it.

Oxford explicitly requires applicants to take and pass the practical component of any relevant science A level. Manchester and Sheffield publish similar requirements. erefore treat practical work seriously throughout the course. They need to:

• attend practical lessons;
• complete required activities;
• maintain appropriate records;
• follow safety procedures;
• demonstrate the required practical competencies.

Strong examination grades do not necessarily compensate for failing a compulsory practical endorsement.

15. Choose subjects in which the required grades are realistic

Medical-school offers are demanding. Standard offers commonly sit around AAA, AAA or AA*A, although contextual and gateway offers may be lower.

Examples include:

• Oxford: A*AA;
• UCL: A*AA;
• Manchester: AAA;
• Cambridge: AAA;
• Sheffield: AAA for its standard offer.

Meeting the minimum grades does not guarantee an interview or place. Applicants may also be assessed through their GCSE record, UCAT result, personal statement information, school reference and interview performance. k themselves an honest question:

Am I likely to achieve the necessary grade in this subject after two demanding years of study?

Enjoyment, teaching quality, prior attainment and willingness to practise all matter.

16. An EPQ can help, but it does not replace required subjects

An Extended Project Qualification can allow a student to investigate a medical, scientific or ethical question in depth.

Possible topics might include:

• antibiotic resistance;
• the ethics of gene editing;
• health inequalities;
• artificial intelligence in diagnosis;
• organ transplantation;
• vaccination;
• dementia care;
• the use of animals in medical research.

The EPQ can develop research, referencing, evaluation, presentation and independent-learning skills.

Some medical schools may make an alternative offer for students completing an EPQ. Sheffield, for example, publishes an AAB plus grade A EPQ alternative under specified conditions. However, the EPQ does not normally replace a required A level such as Biology or Chemistry. mplete an EPQ only when they have the time to produce high-quality work without damaging their three main A-level grades.

17. Build an A-level choice matrix before deciding

A student considering medicine should create a simple table before submitting their sixth-form choices.

Suggested columns include:Medical schoolRequired sciencesAccepted second sciencesStandard gradesRestrictionsOxfordChemistryBiology, Physics, Mathematics or Further MathematicsA*AAThree A levels in the same academic yearUCLBiology and ChemistryThird subject is generally the student’s choiceA*AABoth sciences requiredManchesterBiology or ChemistryChemistry, Biology, Physics, Psychology, Mathematics or Further MathematicsAAAPractical endorsement requiredSheffieldBiology or ChemistryA second accepted scienceAAAFurther Mathematics not accepted for its normal thresholdCambridgeChemistryAdditional science or Mathematics subjectsAAARequirements can differ between colleges

The table should then be expanded to include every medical school the student might consider.

This prevents a common mistake: choosing A levels first and discovering two years later that the combination does not meet the requirements of the preferred universities.

Four sensible A-level combinations

Biology, Chemistry and Mathematics

This is the traditional maximum-flexibility combination. It is suitable for students who are strong in all three subjects and want to keep a broad range of medical schools open.

Biology, Chemistry and Physics

This provides a strong scientific foundation and may appeal to students interested in medical technology, imaging or the physical sciences.

Biology, Chemistry and a humanities subject

This can provide an excellent balance. The student meets the requirements of many medical schools while developing communication, analysis and extended-writing skills.

Biology or Chemistry, another science and a third academic subject

This may meet the requirements of some medical schools, but it creates a narrower list. Students choosing this route must identify suitable medical schools before committing to it.

What if a student is not certain about medicine?

Students who are interested in medicine but not completely certain should consider which combination also supports alternative courses.

Biology and Chemistry can lead towards:

• medicine;
• dentistry;
• veterinary medicine;
• pharmacy;
• biomedical science;
• biochemistry;
• neuroscience;
• pharmacology;
• biological sciences.

Adding Mathematics may keep more physical-science and quantitative courses open. Adding Psychology may support psychology or neuroscience. A humanities subject may maintain options in law, languages, social sciences or arts-based degrees.

The best combination is therefore not only the one that permits an application to medicine. It should also support a realistic alternative plan.

A final checklist for Year 11 students

Before confirming A levels, ask:

1. Have I checked the current requirements of at least eight medical schools?
2. Does my combination include Chemistry?
3. Does it include Biology?
4. If one is missing, which medical schools will still accept my combination?
5. Is my third subject accepted by the universities I am considering?
6. Am I choosing Mathematics because I enjoy it or because I mistakenly believe it is compulsory?
7. Will Mathematics and Further Mathematics be counted separately?
8. Can I realistically achieve at least AAA or the grades required by my preferred courses?
9. Will taking four A levels reduce my chances of achieving excellent grades?
10. Do I have an alternative course or career plan?

A levels are only one part of the application

The correct subject combination makes a student eligible to apply. It does not secure a medical-school place.

Applicants must also prepare for the UCAT, develop an informed understanding of healthcare, reflect on relevant experience and perform well at interview.

For students applying for 2027 entry, the UCAT testing window runs from 13 July to 24 September 2026, and the medicine UCAS deadline is 15 October 2026. Future applicants must check the dates for their own application cycle. For most students in England who are serious about medicine, the safest recommendation remains:

Biology, Chemistry and the third academic subject in which they are most likely to achieve an excellent grade.

Mathematics is valuable, but it is not universally required. Physics, Psychology, humanities and languages can all be sensible choices when individual medical-school requirements have been checked.

The most important step is not following a traditional combination without question. It is researching carefully before making a decision that could shape the range of medical schools available two years later.
