This is my personal opinion. I’ve seen people get 6 at GCSE who get predicted A* in maths and go on to get either an A or A*. Honestly if you’re getting a 7 and 8 in GCSE maths you should be fine. Almost every student I know that does 3 stem subjects, they get A* in mathematics or the highest grade comes In maths. I’ve seen many people struggle with biology or physics because the application is quite hard as maths it’s just the same method each time and there is more of a positive correlation between practising exam questions to scores. Maths is also more satisfying than other subjects as when you get a tricky question right, there’s a much better feeling than getting one in another subject for me. I have seen people get A* in maths and further maths but B in biology and Physics. A level Maths also hands out the highest percentage of A* and A compared to other A Levels. Another reason why maths may benefit you for medicine even though you don’t need it, is for like UCAT and interviews. It’s a section in the UCAT and a lot of unis May ask you stats related questions in your interviews. I know someone who got near all 9’s at GCSE, but they took geography instead of maths at A Level and he got 2450 on his UCAT as he fully flopped the maths section. Yes you do not need maths but in my opinion most people I know say maths is their easiest a level and they simply enjoy revising it compared to others. But the biggest point for you should be DO WHAT FEELS RIGHT FOR YOU, don’t pick maths simply because I’ve listed all these arguments, do it because it’s the subject you want to study and that you think will find comfortable. If you are better suited for Spanish or religious studies or whatever then that’s fine, everybody is different and you don’t want to regret picking an A Level as that’s me with physics, please do what you feel is right for you.
