If you're aiming for a career in medicine or engineering, choosing the right A-level subjects is crucial. Let’s break down the best combinations for each field based on data from top universities and educational resources.

Why A-Level Choices Matter

Your A-level subjects can significantly impact your university applications. Medical and engineering programs are highly competitive, and specific A-levels are often required. According to the Medic Portal, nearly all UK medical schools require Chemistry, while Mathematics and Physics are essential for engineering disciplines.

A-Level Combinations for Medicine

For those interested in medicine, the ideal A-level combination includes:

  • Chemistry: Required by nearly all medical schools.
  • Biology: Important for many schools; taking both Chemistry and Biology opens more options.
  • Mathematics or Physics: Either can serve as the third A-level.
A-Level Requirements for Medicine

A-Level Requirements for Medicine

Core subject expectations at selected UK universities.

University Required A-levels Notes
Oxford Chemistry + (Maths/Biology/Physics/Further Maths) A*AA minimum; excludes Critical Thinking/General Studies
Cambridge Chemistry + (Biology/Maths/Physics) A*A*A; third science recommended
Imperial, UCL, KCL Chemistry, Biology AAA minimum
Others (e.g., Bristol, Glasgow) Chemistry + one of (Biology/Maths/Physics) Some flexibility for the third subject

A-Level Combinations for Engineering

For aspiring engineers, the recommended A-level subjects are:

  • Mathematics: Essential for almost all engineering courses.
  • Physics: Also crucial for engineering studies.
  • Further Mathematics: Highly recommended, especially for competitive programs.


A-Level Core Subjects for Engineering

A-Level Subjects for Engineering

Core and recommended subjects by engineering discipline.

Engineering Discipline Core A-levels Strongly Recommended/Optional
General Engineering Mathematics, Physics Further Mathematics, Chemistry, Computing
Chemical Engineering Mathematics, Chemistry Physics, Further Mathematics
Computer/Electrical Engineering Mathematics, Physics Further Mathematics, Computer Science

Key Insights

  1. Chemistry is non-negotiable for medicine; it is the backbone of medical education.
  2. Mathematics and Physics are non-negotiable for engineering; they form the foundation of engineering principles.
  3. For medicine, the best combination is Chemistry, Biology, and Maths or Physics.
  4. For engineering, focus on Mathematics and Physics, with Further Mathematics as a strong asset.


Additional Considerations

  • Always check the specific requirements of your target universities, as some may have unique preferences for third subjects.
  • Taking a fourth A-level, like Further Mathematics, can enhance your application but is generally not required.
