I just a attended a free webinar about using Mathematica for education (http://www.wolfram.com/services/education/seminars/s01.html) and the guy who was chatting with all of the attendees told me my college already had a site license. Turns out I can use Mathematica at school and at home for free and I had no idea...

You might want to check if your campus has something similar set up. The Mathematica folks might be able to direct you to the right place.
