So I'm planning to take physics chemistry maths and f maths, as I want to study materials science, which needs all (they don't say that both physics and chemistry are 'required', but most people who get into top unis do them, and I want to do f maths as it is considered helpful). At school, I'm not really enjoying chemistry, but with my tutor it's more interesting. I am also getting grade 9s in all of the subjects above, and I really like physics. Do you think that it is OK to take one less enjoyable subject if it opens more doors?
