What Are the Best A-Level Combinations by Subject?
Key takeaways:
Choosing your A-Level subjects is one of the most important academic decisions you’ll make. The combination you choose can directly impact which university courses you can apply for—and how competitive your application will be.
If you're aiming for top universities or competitive degrees like Medicine, Engineering, Law, or Economics, your subject choices matter just as much as your final grades.
In this guide, we’ll explain what the best A-Level combinations are by subject, why they matter, and how to choose the right combination based on your goals.
Why Are A-Level Subject Combinations So Important?
A-Level choices are not just about what you enjoy—they are a strategic decision that can shape your academic future.
Universities assess three key things when reviewing your application:
1. Subject Requirements
Some degrees have strict entry requirements. For example:
- Medicine almost always requires Chemistry + Biology
- Engineering requires Maths + Physics
- Economics typically requires Maths
If you don’t meet these requirements, you may not be eligible to apply.
2. Academic Rigour
Top universities prefer subjects that demonstrate strong academic ability. Traditional, analytical subjects signal that you can handle challenging content and succeed in a demanding academic environment.
3. Evidence of Potential
Your A-Level combination shows how prepared you are for your chosen course:
- Further Maths → readiness for quantitative degrees
- Essay subjects → critical thinking and argumentation
- Sciences → logical reasoning and analytical skills
What Are the Most Respected A-Level Subjects?
Some A-Level subjects are more widely accepted by universities, especially for competitive courses.
These include:
- Maths
- Further Maths
- English Literature
- Physics
- Chemistry
- Biology
- History
- Geography
These subjects are valued because they:
- Keep the most degree options open
- Demonstrate academic strength
- Develop transferable skills like analysis and communication
Key insight:
If you’re unsure about your future degree, choosing at least one or two of these subjects is the safest way to keep your options open.
Best A-Level Combinations for Medicine
