I don't want any of that "Only you can choose your A-level", as I just want to know what other people would do in my situation, but what A-level should I do as my 4th? I am also choosing Maths, Further Maths and Physics, and I intend on doing Physics at uni, and until PhD as I want to become a physicist.
I'm thinking of doing 1 of the following:
Chemistry
English Literature
Geography
French
I've got 9s in all my subjects, but I find Geography the easiest to revise for and I love it as it's also quite interesting. French is the lowest effort and I get 9s without trying, and my teacher really wants me to take it too. Chemistry is really interesting to me and I've done some of the A-level content out of interest and it's really cool and not to hard to comprehend, I also really like the expansion on Organic in A-level. English Lit is interesting to me as I like reading and doing in-depth analysis, and it would fulfil my recommended English work for when I apply to Caltech, though I suppose it's not mandatory. Still, I'd be fine doing it, but it's a bit more effort than the others and not as interesting as I'm more interested in STEM subjects. Even Geography has its scientific elements.
I'd just like to know what other people would do in my case, so I can see a bit more openly here. I'm in Year 10 by the way, which is why I'm asking this quite randomly in the year.
