Yeah, if investment Banking is what you're into then Maths will be one of the best degrees to do, and I know some maths courses have finance modules. But you can do a lot more than that too, I've been speaking to quite a few biologists and the like recently who all say their teams have mathematicians on them and are in high demand, like a neuroscience researcher I was talking to at a christening the other day, whose team leader has a degree in maths. Plus you could always try for GCSQ.
