A journey of a thousand miles begins with a single step. Becoming a doctor is a journey, and selecting the right A-Levels is perhaps the first step a student should take. While there is some room for flexibility, future doctors should keep several subjects in mind.
Requirements vary between medical schools, so there is no single "correct" combination that works everywhere. At the same time, A-levels are not the only way in, as alternative pathways also exist.
In this blog, we will answer 1 of the most common questions aspiring medical students ask: “What A-levels do I need to become a doctor?”
What A-Levels Do You Need to Study Medicine?
Selecting the right A-levels has several components which should be examined with a cool mind and realistic expectations. The decision must include the entry requirements for medical universities, the academic ability of the students, and, last but not least, their personal interests.
What A-Levels Do Universities Require to Study Medicine?
A-levels in chemistry and biology will open most universities' doors. The remaining schools require a third A-level in Physics or Mathematics. You might wonder: Do you need physics to be a doctor? The truth is, not always, but including it (or Maths) makes you eligible for every medical university.
2 subjects are essential for a medical programme: Biology and Chemistry. Students will have fewer universities to choose from if they skip either.
Beyond subject choice, there are also real differences between medical schools in how strictly they apply these requirements. Some universities insist on both Biology and Chemistry at A-level with no exceptions, while others will consider applicants who are missing 1 of these subjects if they can demonstrate equivalent knowledge through another qualification. This is why it's always worth checking the specific entry requirements of each university you're interested in, rather than assuming one school's rules apply everywhere.

What A-Levels Should Students Elect to Study Medicine?
Students often have interests that are not necessarily competitive for medical schools. Psychology is such a subject, and it is an excellent choice for a future psychiatrist. Still, medical schools have no explicit requirement for it, and it might seem like a less-than-optimal choice for admission.
However, if students cover Biology and Chemistry, they still have a broad choice of available universities. Young minds should pursue their interests even if they don’t serve an immediate purpose. That’s how character is built.
Can You Become a Doctor Without A-Levels?
Yes, it is possible to become a doctor without traditional A-levels, although it is a bit less common. You still need an equivalent upper-secondary qualification, and many universities require Biology and Chemistry regardless. Some accept alternatives such as the IB, Access/Foundation programmes, BTEC qualifications, or their own entrance examination.
Generally, universities outside the UK have more flexible entry requirements and place less weight on A-levels specifically.
But why do requirements vary so much between universities? Mainly because each medical school sets its own admissions policy based on how it structures its course, how competitive its applicant pool is, and whether it offers a pre-med pathway (such as a foundation year).
Basically, this means that not having A-levels doesn't automatically rule you out of medicine, but it does mean you'll need to research which universities and pathways are realistically open to you.
How Many A-Levels Do You Need for Medicine?
A-levels are demanding and stressful for students, though not everyone will admit it. Teachers and parents often unintentionally set a high bar for the youth, and young people may put more pressure on themselves than they can handle. The results could be demotivation and even burnout.
There is also the peculiar case of Chemistry. A survey among students and teachers found it to be the most challenging A-level subject. It is difficult to study and get good grades. And it is a vital part of studying medicine.
Thus when it comes to what A-levels for doctor, 3 subjects are usually safe, and most students can handle it. 4 A-levels would be a challenge for everyone but the academically gifted. Therefore, students, parents, and teachers should make this decision together.
In terms of subject combinations, the typical setup is Biology, Chemistry, and a third subject such as Physics, Maths, or a subject of personal interest. University differences matter here too: a small number of universities ask for 4 A-levels, others are happy with 3, and the "right" combination for one applicant may not be ideal for another depending on which universities they're targeting.
Alternative Routes Into Medicine
If traditional A-levels aren't the right fit for your situation, there are several established alternative routes into medicine:
Access to Medicine Courses
These are typically 1-year courses designed for students who didn't take A-levels, or who didn't take the right combination, and want to build up the necessary science knowledge before applying to medical school.
Foundation Year Medicine Programmes
Foundation medicine programmes act as a preparatory year ahead of the standard medicine course, covering core science subjects for students who are missing certain A-levels or who didn't achieve the grades they needed.
Graduate Entry Medicine
For students who already hold a university degree in another subject, graduate entry medicine programmes offer an accelerated route into medicine that doesn't rely on A-level results in the same way as the standard undergraduate route.
International Qualifications
Many medical schools, especially in Europe, will also accept international qualifications such as the International Baccalaureate (IB) or other national school-leaving certificates in place of A-levels, provided the subject content is broadly equivalent.
What are the Best A-Levels for Medicine?
If you're wondering what A-levels do you need to become a doctor or maximise your chances of attending medical school, that would be Chemistry, Biology, Physics, and Math. The first 2 have greater weight with admission offices, while the latter is not as required.
Biology is good because it prepares students for subjects like anatomy, the "backbone" of medicine. Chemistry introduces aspiring doctors to the effects of medications on the human body. Math teaches universal problem-solving skills, and physics provides insight into medical practices and technologies.
There is no knowledge that is not power.
What Grades Do You Need to Study Medicine?
UK medical schools usually require AAA at A-levels; the most preferred subjects are Biology and Chemistry. Physics or Maths are also required in a few schools.
Grade requirements can reach AAA or even AAA, as they are for Cambridge. Few schools allow AAB. University requirements for medicine are highly competitive, and more than 9,000 students don't make it to the admission lists each year.
Because grade requirements can vary a lot from one university to the next, it's important to check the specific entry requirements of each medical school you're considering rather than relying on a single "typical" grade profile. If your grades fall short of a particular university's requirements, it's also worth knowing that A-level resits for medicine are accepted by some medical schools, so a disappointing results day doesn't have to be the end of the road.
Can You Study Medicine Without Chemistry or Biology A-Level?
Chemistry requirements vary significantly between medical schools. Some universities treat Chemistry A-level as a strict, non-negotiable requirement, while others are more flexible and will consider applicants who haven't taken it, particularly if they're strong in Biology and have relevant experience.
Biology requirements also vary, though slightly less dramatically than Chemistry. Most medical schools still expect to see Biology A-level, but a handful of universities, particularly those with a more flexible or international admissions approach, may consider applicants without it.
In both cases, alternative qualifications may be considered in place of the missing subject, such as a related BTEC, an Access to Medicine course, or evidence of equivalent knowledge gained through other study. As with every other entry requirement discussed in this guide, the safest approach is to check the specific policy of each university you're applying to, rather than assuming Chemistry or Biology is always compulsory.
What A-Levels Do You Need to Study Medicine Abroad?
European universities are a lot more flexible in their entry requirements for A-levels. While Biology and Chemistry are top selections, the grade requirements are not as competitive as in the UK.
Furthermore, many European universities accept students with only A-levels, GCSEs, or BTECs. There are no entry examinations nor stressful interviews, and many students choose to study in Europe.

Why This Matters
Medicine is an extremely competitive degree, and 1 of the most common reasons medical applicants get rejected is not meeting their A-level entry requirements. Knowing what A-levels to be a doctor, and making the right choices early, is often the difference between having dozens of universities open to you or almost none.

Frequently Asked Questions
Can I become a doctor with GCSEs only?
GCSEs alone are generally not enough for direct entry to medical school, either in the UK or at most European universities. Medical schools require applicants to have completed upper-secondary education or have an equivalent university-entry qualification, like the International Baccalaureate.
However, studying medicine in Europe does not necessarily mean you need traditional UK A-levels. Depending on the university, alternative qualifications, entrance examinations, or a medicine foundation programme may provide another route into medical school.
Do all medical schools require the same A-level subjects?
No, while Biology and Chemistry are the most commonly required subjects, requirements do vary between universities. Some ask for a 3rd science or Maths A-level, some are flexible on the 3rd subject, and a small number will consider applicants without Chemistry or Biology under certain circumstances.
Can mature students apply for medicine?
Yes, mature students can apply for medicine, often through graduate entry programmes if they already hold a degree, or through standard entry if they have (or are working towards) the right A-levels or equivalent qualifications. Universities will usually look at your most recent academic performance alongside any relevant work or life experience.
Can international students apply without UK A-levels?
Yes. Many medical schools, particularly in Europe, accept equivalent international qualifications such as the International Baccalaureate or national school-leaving certificates in place of UK A-levels, as long as the subject content and grades are comparable
