Hi
@lifeisallgoodlol,
4 A Levels? Damn, definitely looks good for any application and as long as you have good time management, definitely possible.
What I would say about further maths, as already mentioned in the thread, it is typically used for more maths heavy degrees as well as STEM. However, it is very good to bolster your maths A level as a lot of the content learned is also A level maths so it will help you to get a better grade. Especially if you just do it as an AS level (which depending on the exam board, is in some cases just an A level maths in one year).
However, what I would say is that if you are interested in doing PPE or History and Politics, definitely do a politics A level. If you are wanting to hit the top universities they will be more inclined to look at subjects that relate to the course, especially from a personal statement perspective. Not to mention going into the course you will have more of an idea of the content learned as you will have covered some of it already. Especially for a joint honours course, you will get political modules as well as history ones, so best to have both early on already.
As a recommendation as a politics student, I would definitely do A level politics as your 4th choice. A lot of universities vary a lot when it comes to their history modules. So when it comes to subjects like Philosophy and Politics, they typically diverge a lot (while also related) in the content they teach.
If you want to know more from the politics course side of things, do let me know. More than happy to give you an insight.
Koen.
