Unless you need the sciences for uni, i wouldnt take something you arnt interested in youll struggle with content and exams, whilst you are revising you will just want to sleep.. this comes from experiance.
I took psychology thinking id really enjoy it but i hated it, managed to be an A at As so carried it on and this year its ruint me, its so hard to remember when you care so little for it. If its aqa its pure exam based so you cant pull your marks up with coursework.
My only A level i enjoyed was History, but i always have, plus its what my degree will be in. Id reccomend it to anyone who is prepared to put effort in. For me i enjoyed it as youd go to lessson at ungodly hours of the morning and basically be told a story. Although that may be over simplifying a quite difficult subject haha, if you are picking 4, try something like History or English, essay based subjects might end up the most appealing to you😏
I did Law to, but honestly its pretty hideous 😂 read around all the subjects and topics in them each college is different 😋
