Some unsolicited advice here, so take it for what it's worth:
Double-major or at least have a STRONG minor if you choose marketing or advertising. If you have a marketing/advertising major coupled with a finance/accounting minor, you are head and shoulders above the rest of the crowd when talking to most companies. They want creative people, but they also want creative people that have some business sense about them.
I didn't do this and I somewhat regret it as I'm now probably stuck going for a masters before I'm allowed "top floor" access in the company I currently work for. My history and philosophy minors have served me well, but they are a bit out of place for an MIS major...
Furthermore, break your neck to get internships or OJT in your field if you aren't going to school year-round. When you do make it to a university or fully-accredited college, find out about exchange programs and try to do at least one during your undergrad. The program I went through at the Sorbonne and Blaise Pascal/UTEP in France has gotten my resume into doors that it had no business entering many times and typically garners more interest than anything else I did during my college years.
Just my .02 cents...Good luck.
