How to Choose Your A-Level Subjects

Start with three honest questions

Before you look at university lists, ask yourself three things. Which subjects do I do well in, and why? Which do I enjoy enough to work on for two years? Where do I want to go afterwards, even roughly?

The best combination balances all three. A subject you are strong in but dislike can become a grind. A subject you love but find very hard may be fine if you are willing to put the hours in. Choosing a subject only because a friend or a teacher is doing it is rarely a good reason.

What "facilitating subjects" means

You may hear this phrase a lot. Facilitating subjects are those often asked for by universities across a wide range of degrees. The usual list is maths, further maths, English literature, biology, chemistry, physics, history, geography, and languages (both modern and classical). Taking two of them tends to keep many degree options open.

Notice what this does not say. Other subjects, such as psychology, economics, business, computer science or sociology, are respected and are needed for some courses. They are simply less often a requirement across many different degrees. Choosing a mix is perfectly sensible. The point is not to avoid non-facilitating subjects, but to check that your combination fits what you might study.

Check university and course requirements

This is the single most useful step, and the one students leave too late. Entry requirements vary by university and by course, and they change, so always check current information on university websites and on the UCAS course search.

• Medicine usually requires chemistry and often biology, and many courses expect a third science or maths.
• Engineering degrees generally expect maths and often physics. Further maths can help.
• Many science courses ask for the matching A-Level, for example chemistry for chemistry or chemical engineering.
• Economics courses commonly value maths, and some require it.
• Law, history and many humanities degrees often do not require specific subjects, but value essay-based subjects.
• Some courses need a language or a particular GCSE. Check GCSE requirements too.

Pick three real courses you might apply for, open their entry requirements and note the subjects asked for. If two or three of your options point at the same subject, you have your first choice.

If you have no idea what you want to study, that is normal. In that case, a balanced mix of respected subjects, including at least one or two facilitating ones, keeps more options open than a narrow combination.

The jump from GCSE

Almost every student says the same thing: A-Level is a step up. The content is more demanding, the pace is quicker, and you are expected to work more independently. Teachers explain the ideas, but they will not chase you for every piece of reading.

In maths, the move from GCSE to A-Level algebra and calculus is large. In sciences, the maths content increases and explanations must be more precise. In English literature and history, you move from describing what happens to building and defending an argument across a whole essay. In languages, you are expected to speak and write at length with much more confidence.

A useful rule: if you got a grade 7 or above in the matching GCSE, you are usually well placed. A 6 can be fine with effort. A 5 or below in a subject like maths or a science is worth discussing honestly with your teacher before you commit. Individual schools and colleges set their own entry grades, so check theirs.

Understand the workload

Subjects feel different once you study them. As a rough guide, teachers often recommend several hours of independent study per week for each subject, on top of lessons. That can add up to a lot with three or four subjects.

• Essay subjects (English, history) involve heavy reading and regular long writing.
• Maths and sciences involve constant problem practice. Understanding a worked example is not the same as being able to do the question yourself.
• Practical subjects add coursework or lab work, depending on the course.
• Languages need little and often, so regular vocabulary and speaking practice matters more than occasional long sessions.

Try to avoid a combination where every subject is heavy in the same way. Three essay-heavy subjects, or three problem-heavy ones, can leave you tired at the same moments in the year. Do not assume you cannot cope with it, but plan for it.

Taste before you commit

Most students have not studied A-Level subjects like psychology, economics, business or further maths at GCSE, so it is hard to know what they involve. Look at the specification on the exam board website (AQA, Pearson Edexcel, OCR or WJEC Eduqas), read sample papers, and watch a few online lessons. Ask current students what a normal week looks like. Open days are the best moment to talk to subject teachers directly.

Common mistakes

1. Choosing only what you enjoy now, without checking whether it fits your plans.
2. Choosing only what looks impressive, even if you are unlikely to enjoy it or achieve well in it.
3. Taking four subjects without a clear reason when three would let you do better in each.
4. Leaving the decision until results day. Make a main plan and a backup, so a grade change does not leave you stuck.
5. Forgetting that you can change your mind early in Year 12. Most schools allow swaps in the first weeks.

Where extra support can help

If you do pick a demanding subject, getting support early is easier than catching up in Year 13. A tutor can bridge the gap from GCSE, show you how your exam board marks answers, and give you practice with exam questions. Nerdely offers one-to-one online lessons across A-Level maths, A-Level chemistry, A-Level economics and other subjects, with tutors matched to your exam board. Our A-Level page lists them all.
