A-Level Choices.

I don't know a lot about it, but I think they'd be alright. Where are you looking to apply to? They should be good, provided you have wrk experience. If you can, Maths might be good instead of Economics, but I don't think Economics would disadvantage you. English is probably a good choice (essay subject and all).

Biology and Chemistry are a good combo to have, they overlap in some modules which makes things a little easier and of course they link with your future career choices. As nombo said maths would probably be better suited rather than economics. Just make sure you are passionate/interested about the subjects you want to take, otherwise you might begin to hate it and not put much effort in (which is what happened to me)

Ok, if you're struggling, it's probably best you don't take it then - a B in Maths wouldn't look as good as an A in Econ. If you're not Oxbridging, it probably won't matter as well...you sound pretty set to me! Good luck x

Chemistry and Biology are needed and maths would be good if you're applying to Oxbridge (maybe UCL and ICL?), but don't do maths if you don't enjoy it. Do what you like!

For medicine, many universities (UCL and St George's) like a contrasting humanities such as history or language subject, so english or economics works I guess.

Overall, think about what you're best at combined with what you enjoy!

As somebody already said, take subjects you know you can get an A in. If you find Economics easy, stick with it if Maths isn't your favourite. Maths is NOT required to get into Medical school. If you have Biology and Chemistry, just make sure you get all A grades.
