If your child wants to study medicine, the subject choices at IGCSE are the first domino. Get them wrong and the path closes before A-Levels even begin.
This guide sets out the exact Cambridge IGCSE and Edexcel IGCSE subjects required for a medicine pathway — including what is compulsory, what is strongly recommended, and what grade expectations look like for medical schools in the UK, UAE, Malaysia, Singapore, Ireland, and Europe. Whether your child is choosing Year 10 subjects now or preparing for the exam series ahead, this is the most practical guide available.
Medicine is one of the most competitive degree programmes in the world. Entry requirements are precise and largely non-negotiable. And the chain of prerequisites runs all the way back to IGCSE — which means a 14-year-old's subject choices at the start of Year 10 directly shape whether a medical school application is even possible six years later.
This guide sets out exactly which IGCSE subjects are needed for a medicine pathway, which are strongly recommended, and what grade expectations look like at each stage.
Three subjects are effectively compulsory for any student targeting medicine. Without them at IGCSE, the A-Level subjects required for medical school entry are not accessible.
The most directly relevant science for medicine. IGCSE Biology covers cell biology, genetics, human physiology, immunity, and disease — all of which are foundational to medical study. Without IGCSE Biology, A-Level Biology (required by virtually every medical school) is difficult to access. Some schools allow students to begin A-Level Biology without IGCSE Biology, but the content gap is significant and the risk is real.
A-Level Chemistry is required or strongly preferred by the majority of medical schools worldwide, including all UK medical schools. IGCSE Chemistry is the prerequisite. Students who take Combined or Coordinated Science instead of separate Chemistry at IGCSE may find A-Level Chemistry challenging, as the single-subject IGCSE provides a more complete foundation.
Not directly required for medicine, but essential for maintaining A-Level options and for the quantitative elements of medical training and medical entrance exams (BMAT, UCAT, MCAT). Extended tier, not Core. A student targeting medicine who takes Core Mathematics is significantly limiting themselves.
Biology, Chemistry, and Mathematics (Extended) are essential for a medicine pathway — without them, A-Level Biology and Chemistry (required by virtually all medical schools) are inaccessible. Physics is strongly recommended. All three sciences should be taken as separate subjects, not Combined Science.
Not required by most medical schools, but recommended for two reasons. First, it provides access to A-Level Physics, which some medical schools in the UAE, Malaysia, and certain European countries expect. Second, medical school entrance exams — particularly the BMAT and IMAT — include physics-based questions. A student without any physics background is at a disadvantage in those assessments.
Every medical school requires strong English Language. In countries where English is not the first language — UAE, Malaysia, Qatar, Kuwait, Egypt — a strong IGCSE English grade is often specifically requested as evidence of language proficiency alongside IELTS or equivalent. It is also non-negotiable for UCAS applications to UK medical schools.
| Region / Country | Key IGCSE Requirements | Grade Expectations |
|---|---|---|
| UK (all medical schools) | Biology, Chemistry, English, Maths | Typically A or A* in sciences |
| UAE (UAE University, Sharjah, Gulf Medical) | Biology, Chemistry, Maths, Physics | A* in sciences typically expected |
| Malaysia (UM, UKM, Monash, IMU) | Biology, Chemistry, Physics, Maths, English | A and A* across all sciences |
| Singapore (NUS Medicine) | Biology, Chemistry, Maths, English | Very high — top-band scores expected |
| Ireland (RCSI, UCD) | Biology, Chemistry, English, Maths | A in sciences; HPAT also required |
| Europe (Czech, Hungary, Romania) | Biology, Chemistry, Physics | Varies — entrance exam weighted heavily |
The pattern across all regions: Biology and Chemistry at IGCSE, with strong grades — A or A* — in both, are the consistent requirement. Physics and Mathematics are the recommended additions. English is essential for non-native English speakers applying to English-medium programmes.
Medical schools see IGCSE results as a proxy for academic capability. A student who achieves A* in Biology and Chemistry at IGCSE has demonstrated not just knowledge of those subjects, but the kind of sustained, precise academic performance that medical school requires across six or more years of training.
A student who achieves B grades in the sciences at IGCSE is not automatically disqualified from medicine. But their A-Level trajectory needs to be more compelling. Admissions teams notice when IGCSE science grades are lower than A-Level science grades — it raises questions about whether the A-Level results reflect genuine performance or generous teacher predictions.
The honest implication: if your child is targeting medicine, the sciences at IGCSE should be taken seriously from the beginning of Year 10. Not Year 11. Not in the final months before the exam. From the start.
For students taking the IB Diploma rather than A-Levels, the requirements translate directly. Most medical schools expect Biology HL and Chemistry HL, with Mathematics at SL or HL depending on the institution. The IGCSE prerequisites for those IB subjects are the same as for A-Level: Biology and Chemistry at IGCSE are the foundations.
IB students targeting medicine who did not take separate Biology and Chemistry at IGCSE — who took Combined or Coordinated Science instead — may be allowed to begin HL Biology and Chemistry, but the preparation gap needs to be addressed early in DP1 before the content becomes overwhelming.
Most medical schools do not specify IGCSE grades in their formal entry requirements — they focus on A-Level or IB results and entrance exam performance (UCAT, BMAT, or equivalent). However, IGCSE science grades influence two things that do matter: the A-Level predicted grades your child receives, and the strength of the academic profile reviewed holistically. A student with A* in Biology and Chemistry at IGCSE receives more confident predicted grades than a student with Bs. Those predicted grades determine which medical school offers arrive. For guidance on achieving top grades, see our post on how to get an A* in IGCSE Maths.
Separate Biology, Chemistry, and Physics at IGCSE is significantly better than Combined or Coordinated Science for a medicine pathway. Combined Science covers the same broad topics but at lower depth and without the subject-specific rigour that separate sciences provide. Students who take Combined Science and then attempt A-Level Biology or Chemistry face a real content gap in the foundational knowledge those courses assume. Some schools offer only Combined Science — if that is the case, targeted subject-specific tutoring in Years 10 and 11 is strongly recommended to compensate.
Students taking the IB Diploma route to medicine need Biology HL and Chemistry HL. Those HL subjects build directly on IGCSE Biology and Chemistry. A student who took Combined Science at IGCSE rather than separate Biology and Chemistry will need to address content gaps at the start of DP1 before the pace of the HL courses makes catch-up difficult. The IGCSE subjects for medicine are the foundation for both the A-Level and IB medicine pathway — the choice of qualification comes later, but the subject choices at IGCSE must be right either way.

They are the students whose Year 10 was genuinely structured, whose understanding of the content was solid before the revision phase began, and whose past paper practice in Year 11 was analytical rather than anxious.
If your child is in Year 9 and medicine is the aspiration, the time to think carefully about IGCSE subject selection and preparation is now. The path to medical school is long. The first step is the right subjects, taken seriously, from the very beginning.
Physics is strongly recommended but not universally required. Some medical schools in the UAE, Malaysia, and Europe expect Physics at IGCSE level. UK medical schools do not typically require Physics IGCSE specifically, but it provides access to A-Level Physics which some programmes prefer, and covers content tested in medical entrance exams like BMAT.
In practice, taking A-Level Biology without IGCSE Biology is very difficult — the content gap is significant. Most sixth forms require at least a B in IGCSE Biology for A-Level Biology entry. A student who did not take Biology at IGCSE would need to demonstrate equivalent knowledge through another route before being accepted onto A-Level Biology.
While medical schools focus primarily on A-Level or IB results, IGCSE science grades of B or above are typically needed to access A-Level Biology and Chemistry. A* grades in the sciences support stronger predicted grades at A-Level, which directly affects medical school offers. Most successful medicine applicants have A and A* grades across their IGCSE sciences.
