Firstly, congratulations on your amazing results!
As for the A-level choices, they're extremely varied, which can be a good and a bad thing. As your not completely sure what you're wanting to do yet in terms of future education (Which, you shouldn't really stress out about at his point) these variety of subjects are a great thing!
For example, Psychology falls in perfectly to teaching, sport science and nursing, it's a extremely varied subject that covers various sectors. It's a subject I'd highly recommend to study.
English Lit falls into teaching nicely
Physical Education clearly falls into sport science nicely
And business studies is an all rounder. It teaches you some good life skills in terms of understanding businesses and in some cases, finance (depending on the exam board)
I would say your choices cover what you are planning to do, however, if you don't have an interest for Psych or Business, they'll prove them self to be more difficult. If you're utterly against the idea of these two subjects then you have to make it clear that you're just not willing to do them as you'll under-perform due to the lack of interest. However, I think it would be worth while to look into the two subjects specifications and maybe some past papers, to see what you think of them.
At the end of the day you have no reason to panic, if you're not in support of these subjects the teachers cannot force you to choose them, and if you're willing to branch out and try something you may not have considered before, then you may enjoy it
If you're just looking at it in terms of what will suit for the future, the majority of courses at university do not specify (Unless you're heading for specific subjects in top Russel Groups of course) the subjects they require. Most just ask for grades
I hope this was of some help and I wish you the best of luck in your AS year!
