if you don’t need it specifically for your university degree is it worth even trying? given how hard it is to get decent grades
As someone in their second year, i would recommend only doing it if you need it. Its a LOT different to GCSE in the depth you have to know and you also have to write an essay as part of paper 3 that is structured differently to an english essay for example so you have to learn how to write in that way on top of learning content.
But all in all, you need to pick subjects that you won't ultimately regret picking and if you have long lasting doubts then maybe its not for you. E.g. i wish i didn't pick chemistry cos i didn't really need it and its never really been a subject i entirely love!
