Number one, single most important thing to consider before taking out ANY student loan is to ask yourself one simple question, and answer it honestly:
"Will the degree I intend to get make me employable enough that I'll be able to find a job that pays well enough to pay off this loan?"
We've all seen the arts majors and political science majors and such who financed 100% of their education, then acted shocked to learn that those things don't exactly show up as credentials in job listings very often. Those are the people who end up on the news, working at Starbucks, bitching because they can't pay off their loans.
Student loans are like any other investment loan; if the final result will not cover the expense of getting there, then do not do it.
