You might be tempted to think that the more A-levels you have, the more impressive your university application will be. Five qualifications are better than three, right? Well, not necessarily. Bear in mind that the more courses you do, the less time you will have to spend on each one, and the harder it will be to get those top marks. Remember that universities only require you to take 3 A-levels—and 3 A*s is certainly more impressive than 5 Bs!
There are some cases in which it may be useful to take an extra subject. Students taking both Maths and Further Maths often choose to take 4 A-levels rather than 3; for example, Physics, Chemistry, Maths, and Further Maths. Top tip: if you think you may want to study a Science or Maths-related subject at university, make sure you check the entry requirements at different universities. For Cambridge, Further Maths A-level is a compulsory requirement for subjects such as Maths and Computer Science, whilst at Oxford it is not essential but recommended.
If you’ve decided already what degree you would like to apply for, congratulations! Do bear in mind that your preference might change depending on what A-level course you enjoy the most. In the majority of cases, if you want to study a subject at university you should probably study it at A-level, and for some subjects it is compulsory (again, check the entry requirements). This holds true primarily for very common A-level subjects such as Maths, Physics, or English Literature. For less common Humanities subjects such as Theology, Philosophy, or History of Art, universities will not expect or require you to have taken the A-level, so just make sure you take at least one other essay-based A-level and research your chosen degree subject as much as you can. If you’re interested in Classics but your school doesn’t offer Latin or Greek, don’t worry— many universities, including Oxford and Cambridge, have Classics courses specifically for those with no prior knowledge. Modern language degrees in particular, such as Russian or Japanese, are often offered ab initio, meaning that you’re not expected to have studied the language at all when you arrive—but bear in mind that you will be required to have taken an A-level in a different modern language such as French to demonstrate your aptitude for languages.
This is completely normal, lots of other students will be in your position. Start by considering whether you’re more interested in Science or Humanities subjects, as within these categories most subjects will be useful for whatever application you go on to make; for example, a History A-level will be useful for an English Literature degree, and vice versa. Think carefully about what you enjoyed studying at GCSE, and don’t let others influence your choice too much. The more genuinely interested you are in a subject, the harder you will work and the more convincing you will be in an interview. Unlike the systems in some other countries, the A-level system allows you to drop subjects you don’t like after GCSE and only focus on your favourites—so make sure you take advantage of this!
