How to Choose the Right A-Level Subjects for University
The subjects your child picks at A-Level can open or close university doors. Here's how to get it right.
January 25, 2026 · By the Unitors Team
Choosing A-Level subjects is one of the most consequential decisions a student makes before university. Pick the wrong combination and certain degree programmes become unavailable — no matter how good the grades. Pick the right ones and doors open at the world's best universities. Here's how to navigate the decision intelligently.
Start With the End Goal — Not the Subjects
The biggest mistake families make is choosing subjects based on what the student enjoys or what their friends are taking, without checking whether those subjects actually meet university entry requirements. Before selecting anything, research two or three potential degree courses at the target universities. Find the specific subject requirements and facilitating subjects they prefer. Then work backwards.
Medicine (UK)
Typically requires Chemistry + Biology, plus one of Maths or Physics. Most top medical schools (Imperial, UCL, Edinburgh) will not consider applications without Chemistry.
Check: UCAT, BMAT requirements per school
Engineering
Maths is essential — Further Maths is strongly preferred for top programmes (Imperial, Cambridge, UCL). Physics is required for most engineering disciplines.
Check: whether FM is preferred or required
Law
No specific subjects required, but essay-based subjects (History, English Literature, Economics) demonstrate the analytical and writing skills top law schools value.
Check: LNAT requirement for top UK law schools
Economics / Finance
Maths is essential for most Economics degrees. Further Maths is advantageous. Economics A-Level itself is helpful but not always required — some universities prefer pure Maths over Economics.
Check: individual university requirements vary
The Russell Group's "Facilitating Subjects"
The Russell Group — the UK's 24 leading research universities — has identified eight "facilitating subjects" that keep the most degree options open. If your child doesn't yet know what they want to study, choosing two or three from this list is a safe strategy:
Subjects like Art, Media Studies, PE, and General Studies are not facilitating subjects — this doesn't mean they're bad choices, but they should be chosen alongside facilitating subjects, not instead of them.
How Many A-Levels Should Your Child Take?
The standard is three A-Levels — this is what almost all UK universities expect, and what most university offers are based on. A fourth A-Level is generally not necessary and can harm performance if it spreads effort too thin.
The exception is Further Mathematics — if your child is aiming for top engineering, mathematics, or physics courses, a fourth A-Level in Further Maths is usually worth the extra workload and will significantly strengthen their application.
What If Your Child Is Applying to US Universities?
US universities (including Ivy League schools) don't have the same prescribed requirements as UK universities. They value breadth — a student who takes challenging A-Levels across humanities and sciences is often more competitive than one with three science A-Levels alone.
However, for STEM-heavy US programmes (MIT, Caltech, engineering at Cornell), strong Maths and science A-Levels are expected. Grades matter less than at UK universities — a strong GPA, SAT/ACT score, and extracurriculars can compensate — but the academic profile still matters.
What If Your Child Is Undecided?
This is more common than parents realise, even at Year 12. If your child genuinely doesn't know what they want to study, the safest approach is:
Include Maths — it keeps science, engineering, economics, and computing options open without closing humanities doors.
Pick subjects they're genuinely strong at — passion and ability are more important than perceived prestige. A B in a challenging subject is worse than an A* in one that suits them.
Avoid closing doors unnecessarily — don't take three purely arts subjects unless they're certain they want an arts degree. Keep one science or Maths in the mix where possible.
The Role of a Tutor in Subject Choice
Our tutors at Unitors regularly advise families on A-Level subject combinations — not because it's part of the service, but because it naturally comes up. A tutor who knows your child's strengths and weaknesses in a subject is often better placed than a school counsellor to give an honest assessment of whether they're likely to thrive in it at A-Level. Don't be afraid to ask.
Key Takeaways
- Research specific university entry requirements before choosing subjects.
- Include at least two facilitating subjects if the degree path is unclear.
- Three strong A-Levels beat four mediocre ones — every time.
- Choose subjects your child is genuinely strong in — grades matter more than perceived prestige.
- Seek guidance early — Year 10 is not too soon to start thinking about this.
