Blog Summary
Which subjects are needed to become a doctor? The core subjects are Biology, Chemistry, and either Physics or Mathematics, plus English. Biology and Chemistry are compulsory for almost every medical school, Physics or Mathematics is usually required as a third science, and English is essential as the language of instruction. Below we explain why each subject matters, what grades you need, and how to get into medical school once you have them.

The Core Subjects You Need to Become a Doctor
To study medicine, you need to build your secondary-school programme around the sciences. The subjects that matter most, in order of importance, are:
- Biology — the study of living organisms and the human body; the foundation for anatomy, physiology and genetics. Effectively compulsory.
- Chemistry — the science behind biochemistry, pharmacology and how drugs work in the body. Also effectively compulsory.
- Physics — underpins physiology, medical imaging, radiology and cardiology; often required or strongly preferred.
- Mathematics — needed for dosing, statistics and interpreting research; accepted in place of Physics by some schools.
- English — required as the medium of instruction and for clear communication with patients and colleagues.
Why These Subjects Matter for Medicine
Medicine is an applied science, so the degree assumes you already understand the fundamentals. Biology explains how the body works in health and disease. Chemistry explains what medicines are and how they act.
Physics and Mathematics give you the quantitative thinking behind physiology, imaging and evidence-based practice. English lets you learn, write and, crucially, communicate with patients. Choosing these subjects early keeps every medical pathway open to you.
Compulsory vs Recommended Subjects
It helps to separate the subjects you must have from the ones that strengthen your application:
| Subject | Importance for Medicine |
|---|---|
| Biology | Required by most medical schools |
| Chemistry | Required by most medical schools |
| Physics | Required or strongly recommended by many medical schools |
| Mathematics | Required or accepted as an alternative to Physics by some institutions |
| English | Required as the language of instruction |
Students should always check the current entry requirements of the medical school they plan to apply to.
What Grades Do You Need in These Subjects?
Choosing the right subjects is only half the job medical schools also want strong grades in them. Because medicine is highly competitive, you should aim for high passes in Biology, Chemistry and your third science rather than minimum passes.
At the school-leaving stage this typically means good O-level credits followed by strong A-level (or equivalent) results in the sciences. Students can also learn more about how many points you need to study medicine.
Do You Need Physics to Become a Doctor?
Not always. Physics is required or preferred by many medical schools, but a number will accept Mathematics in its place, provided you keep Biology and Chemistry.
If you are unsure whether Physics is essential for the schools you are targeting, choose it anyway where you can it keeps the most options open. The two subjects you should never drop are Biology and Chemistry.
What If Your Subjects or Grades Fall Short?
If you did not take the ideal subject combination, or your grades are just below the bar, you are not out of the running. A pre-medical or foundation year lets you build the required science base and progress into a medical degree.
This is a common, recognised route for students who decided on medicine late, changed subjects, or need to strengthen their results before applying
From Subjects to Medical School: Your Next Step at TAU
Once you have the right subjects, the next step is entry into a medical programme. At Texila American University (TAU) in Zambia — accredited by the Higher Education Authority (HEA) and approved by the Health Professions Council of Zambia (HPCZ) — there are two clear routes:
Direct MBChB entry. With A-levels in Physics, Chemistry, Biology and Mathematics (or an equivalent pre-med qualification), you enter the five-year MBChB directly.
HPFP foundation route. With Grade 12 / GCE results including English, Mathematics, Biology and Science, you begin with the one-year Health Professions Foundation Programme (HPFP), then progress into the MBChB.
Both routes lead to the same MBChB degree and the same goal: registering as a doctor. The HPFP in particular is designed for students whose subjects or grades need strengthening before medical school.
Choose Your Subjects Early and Aim High
The subjects needed to become a doctor are settled and consistent: Biology, Chemistry, Physics or Mathematics, and English. Choose them as early as your school system allows, work for strong grades, and keep a foundation-year route in mind if you need it.
Get the subjects right, and every path to becoming a doctor stays open.

FAQ’s
Which subjects are needed to become a doctor?
Biology, Chemistry, and either Physics or Mathematics, plus English. Biology and Chemistry are compulsory almost everywhere; Physics or Mathematics is the usual third science; English is required as the language of instruction.
Do you need Physics to become a doctor?
Not always. Physics is required or preferred by many schools, but some accept Mathematics instead, provided you keep Biology and Chemistry. Choosing Physics where you can keeps the most options open.
Which two subjects are compulsory for medicine?
Biology and Chemistry. These are effectively compulsory at almost every medical school and should never be dropped if you want to study medicine.
Do you need Mathematics to study medicine?
Most medical schools require Mathematics, either as a core subject or as an accepted alternative to Physics. It supports dosing, statistics and research skills used throughout medicine.
What if I don’t have the right subjects for medicine?
You can take a pre-medical or foundation year, such as TAU’s one-year HPFP, to build the required science base and then progress into the MBChB medical degree.
Glossary
Medical Admissions Glossary: Key Terms Explained
Before applying to medical school, it helps to understand the terminology used by universities and admissions boards. Below are the standard definitions of key academic tracks, requirements, and entry routes.
MBChB (Bachelor of Medicine and Bachelor of Surgery): The standard undergraduate medical degree awarded by universities in Commonwealth-influenced systems (equivalent to an MD in the US). It qualifies graduates to begin clinical practice after completing their internship.
Pre-Medical Qualification (Pre-Med): A foundational academic pathway or undergraduate degree focusing heavily on biological and physical sciences, designed to prepare students for the rigorous curriculum of medical school.
HPFP (Health Professions Foundation Programme): A specialized one-year preparatory course that bridges the gap between high school (Grade 12/GCE) and a direct medical degree, reinforcing core science and math competencies.
Compulsory Subjects: The mandatory academic courses required by an institution for admission. For medical programs, Biology and Chemistry are globally recognized as the foundational compulsory subjects.
HEA (Higher Education Authority): The official regulatory body responsible for accrediting, supervising, and ensuring quality standards across higher education institutions within a specific country or region.
HPCZ (Health Professions Council of Zambia): The statutory regulatory agency that registers health professionals, accredits medical training facilities, and ensures clinical education meets national healthcare safety standards.
A-Levels (Advanced Levels): Subject-based qualifications taken by students in the final two years of secondary school, widely used by international medical faculties to determine eligibility for direct-entry degree programs.
