Investing student loans?

[Bill 1337]

I'm going off to college and my tuition is free with financial aid and my grandparents are paying for my dorm/meal plan. My poker winnings can easily cover the other expenses.

I was wondering if it would be wortwhile to take out a student loan (5% interest) and invest it? I was thinking putting the money in a high yield savings account which would be like 6% interest. Also paying back the loan would help build credit. Any thoughts?
