I'm starting AS levels pretty soon, and my confirmed chosen subjects are physics and maths, however with my 3rd option I'm not really sure if I should pick chemistry or english. I find chemistry to be very hard even at the supposed "easy" gcse level and it will get much worse in as and a levels, phy and maths will too but I can push through as I'm fond of those subjects. Chemistry drained me even at gcse's however I think picking chemistry would be a better option for uni applications to either mech/aero eng.
But then again, I'm not sure if I can get a good grade in chem, with english however, I can guarantee a good grade and it'll also be good for me as I enjoy it. The problem is unis though, I'm not sure if they'd accept me with Phy, Maths and Eng, and taking english would probably put me at a disadvantage compared to other applicants.
