Which A-Levels Should My Child Take? The 2026 University Entry Guide
A-Level choices made at the end of Year 11 can close university doors years later. This guide gives parents the complete framework for making the right decision, including what specific degree courses actually require.
Most families approach the A-Level decision with one central question: what does my child enjoy? That is a genuine and important input. But treating it as the only input, and ignoring what specific degree courses require, what universities look for, and what doors different subject combinations keep open or close, leads to outcomes that are both predictable and avoidable. This guide gives you the complete framework.
1. The Decision That Quietly Closes University Doors
A-Level subject choices made at the end of Year 11 can close university doors that will still be firmly shut three years later, when your child is sitting in front of a laptop filling in a UCAS form and realising what they cannot apply for. This is not a theoretical risk. We see it happen to real students every single year. And unlike most academic setbacks, it is extremely difficult to reverse.
A student who drops Chemistry at the end of Year 12 has, in almost all cases, permanently closed the door to Medicine. A student who chooses three non-facilitating subjects and then discovers in Year 13 they want to study Engineering often cannot. These decisions cannot be undone at the UCAS stage.
The complete framework for this decision has three components: choose subjects your child is genuinely passionate about and performs well in; ensure those subjects satisfy the entry requirements for their most likely degree directions; and get the support needed to achieve the strongest possible grades. All three matter. The third is often underemphasised.
2. The Facilitating Subjects
The Russell Group publishes guidance on what they call facilitating subjects: the A-Levels most commonly required or preferred by the broadest range of competitive degree courses. Students who take at least two facilitating subjects keep the widest possible range of university options open.
Taking two facilitating subjects is not a requirement. It is a strategy. It means that if your child's interests evolve between Year 11 and their UCAS application, the number of directions still available to them is maximised. Interests change. Subject choices cannot.
3. What Specific Degrees Actually Require
Facilitating subjects tell you what keeps options open broadly. But if your child has a likely direction already, the question becomes more specific: what does that particular degree route actually require?
| Degree | Effectively Required | Strongly Preferred |
|---|---|---|
| Medicine / Dentistry | Chemistry | Biology + Maths or Physics. Without Chemistry, this path is closed at 95%+ of UK medical schools. |
| Engineering (Mechanical / Civil) | Maths + Physics | Further Maths at top universities. Standard requirement virtually universally. |
| Engineering (Chemical) | Chemistry + Maths | Physics or Biology. Check individual university requirements. |
| Computer Science | Mathematics | Further Maths (Imperial, UCL, Cambridge). Not formally required everywhere but strongly preferred at top universities. |
| Economics (Russell Group) | Mathematics | Further Maths advantageous. Some courses now effectively require it through high-level statistical content. |
| Law | No fixed requirement | English Literature, History, Politics. Strong GCSEs and personal statement equally important as subject choice. |
| Medicine at Oxbridge | Chemistry + Biology + Maths | Exceptional GCSE profile also required, plus strong UCAT score and exceptional interview performance. |
For Medicine specifically, Chemistry is effectively non-negotiable at 95%+ of UK medical schools. A student who drops Chemistry at the end of Year 12 has, in almost all cases, permanently closed this door. This decision is very rarely reversible once the first year of A-Levels is underway.
4. The "Easy A-Level" Myth That Costs Students
Every year, some students choose A-Level subjects primarily on the basis of perceived difficulty. This is a rational short-term strategy and a long-term mistake.
Universities, particularly selective ones, are aware of the perceived hierarchy among A-Level subjects. A student with AAA in subjects perceived as less academically rigorous is, in many competitive admissions processes, considered a less strong candidate than a student with ABB in Mathematics, Chemistry, and History.
The Short-Term Thinking
The Right Strategy
"An easier subject chosen for a better predicted grade that closes important university doors is not a good trade. An academically demanding subject with expert support, leading to a strong grade that keeps all options open, usually is."
5. Frequently Asked Questions
My child has no idea what they want to study. What should they take?
Take at least two facilitating subjects, the ones your child is strongest at and most engaged by. Add a third that genuinely interests them regardless of facilitating status. This keeps the most options open without forcing premature specialisation into a field they may not be sure about yet.
Is Further Maths worth taking?
For students targeting Engineering, Physics, or Mathematics at competitive universities, the answer is strongly yes. For most other routes, regular A-Level Maths is sufficient. Further Maths should only be chosen by students with genuine Grade 8 or 9 GCSE Maths ability and real enthusiasm for the subject. It rewards genuine mathematical interest. It can also be counterproductive for students who choose it primarily for UCAS optics.
Can A-Level subjects be changed after starting Year 12?
Within the first three to four weeks of Year 12, usually yes. After that, switching becomes very difficult and sometimes entirely impossible: curriculum content gaps are too large to bridge. Treat the end-of-Year 11 decision as effectively final and get proper advice before making it.
My child wants Medicine but is in Combined Science. Is it too late?
This is manageable in some cases but requires specific, personalised advice based on exactly where your child is now, which year group they are in, and which medical schools are being considered. Do not assume it is either impossible or fine without getting proper guidance. Contact us urgently if this is your situation.
My child's school has a limited A-Level offer. What can we do?
This is more common and more manageable than many families realise. Independent centres, online providers, and further education colleges allow students to take additional A-Level subjects alongside their school's offer in some circumstances. Contact us to discuss the specific options for your situation.
