I'm choosing bio and chem for A-levels but I don't know which of the above three (psych, phy or math) I should choose as a 3rd subject. Context; my goal is to do medicine, and I get all A*s in my subjects except for those three which always fluctuates between A and B. I don't mind choosing any between those 3 subjects, but I wanted to know how hard it gets from the transitions of Yr11 to Yr12 and then Yr12 to Yr13 (i.e does it get harder from the beginning of Yr12 or does it have a step up at Yr13 onwards?) To anyone doing any of the three (or even all three), how are you finding the subjects, what areas of it are the hardest and what is your advice for someone like me? And honestly what do y'all think would help me in the long run? Because surely one of those three subjects would be an advantage when I'm actually doing a Medicine Degree right? (i.e there may or may not be heavily essay based stuff in which psych would be good, or if it's more problem solving then maths or phy would be helpful, you get what I mean?) Before anyone says, "Choose something you enjoy, your 3rd subject doesn't matter unless you're going for Cambridge" — 1. I don't have ANY subject that I enjoy, so might as well choose something that would be helpful 2. I'm not planning on going to Cambridge but I still want something that will prove extremely useful for me once I start studying medicine
