Best major for breaking into banking from non-target
I go to a school that is not a target or a low target for finance (JHU) and I'm wondering what course of action will give me the best chance of getting a position at an IBank (preferably in Sales and Trading). Right now I've accumulated enough credits to graduate with a degree in either CS, applied math, or (pure) math. They're all about equally interesting to me.
While math is definitely the hardest major of those three, Applied Math has a lot of coursework directly related to finance. Would that sort of coursework help when looking for a front office position?
