I'm taking Chemistry, Physics, and Maths at A-level. However I'm not quite sure about the 4th option. Originally I wanted to do Geography, but now I'm thinking about future career prospects and whether to choose a different subject that will better suit this. I got 4A*s, 4As, and 2Bs in my GCSEs. For the 4th option I'm not too sure whether I want to do Geography, Further Maths, or Economics. I'm a bit worried as to whether Further Maths is going to be too hard though.
Any advice would be appreciated. Thanks.
