I'm pretty sure you dont have to have a Finance (or something) degree in order to go into the finance part of work. I have a friend who has a degree in Biology ( got a*(maths) a(bio) b(chem I think?) at A level and he's now an accountant. But in order to get into the higher parts of his job he now has to do all the (professional is what some people call it) accounting/work style exams in order to be a fully qualified accountant and get a higher salary.
