Economics, Mathematics, Drama and English Literature.
Economics is something I'd like to do in university but I also really like Drama as well. What do you think?
It really doesn't matter that much if you have an 'odd' A Level combination, as long as you're enjoying them and fulfilling the entry requirements of the course you're thinking of applying to. Have a look on the websites of some of the universities and their offered courses you're interested in, see if they favour any particular subjects at A Level. As long as you have them, you're fine. I know some economics courses favour maths quite a lot, so you seem to be on the right track!
