I was in the exact same position you are now. I went to the University of Florida and received a degree in finance. I have always had an interest in computers, physics, and mathematics. It took me three years to finally make the decision to go back to school. I am now pursuing a second and third BS (mathematics and physics), however, I am applying to grad school for 2009. I am hoping that the work I have done since returning to school will be enough to get me into a program for which I don't have an undergraduate degree. My recommendation is this: If you are really interested in mathematics and computer science, pick up a copy of How to Prove It by Daniel Velleman. Work through every single problem. If you don't enjoy doing the proofs, scratch mathematics off of your list. I can't speak about the computer science side of things, but maybe someone could add a respone to mine for a suitable computer science book.
