so recently I decided I want to do biology, chemistry, maths and physics for AS but then drop physics in second year, my teachers have told me not to do all three sciences because it probably will be hard but I really want to. so I'm like 100% confused as to what I want to do
I know a few people who do all 3 sciences and one does maths too (I do bio and chem) and the one doing maths really struggled and dropped out but the others did fine and are really enjoying it! As long as they are subjects you enjoy and are really willing to put a LOT of effort in, you should be fine!
From experience chem is a lot of applications and maths but not too much content but biology is a lot of application and content but not much maths.
