The biggest favor you can do yourself is to learn as much about the business as possible. The best way to do this now (if you have the time) is offer to intern for the firm and/or a broker. You might have to intern without pay, but a couple of months of this will give you a good idea of what it's like.

I would also read and learn the material for the Series 7.

Also, try to get a good, basic foundation in economics; if you don't have one already.

You have my sympathies. I graduated with a BS in Political Science and it's the most worthless degree there is. I enjoyed it immensely, but as far as having any real world practical application, forget it! I've now made it one of my personal missions in life to urge each college student I meet to get a real, practical skill in college. Minor in what you enjoy, major in what you can make a living at!

I disagree with Doberman.  I think every student should get a liberal arts degree, or at least a good liberal education.  Teach students how to read critically and for real retention, to write, to do math (including time value of money and finance problems in addition to the calculus), and TO THINK FOR THEMSELVES.  Do you really think that all of those jackoffs running around with Communications, Marketing, and Business Administration degrees have something on you?  Give yourself more credit than that.  As for you insanehero, I’d hire you any day of the week over someone with a business degree.  Good luck to ya!
