You MIGHT get a refund check - it would depend upon the COST of your classes and the AMOUNT of aid you qualify for. If you stick to just "gift" aid - State & Federal grants and scholarships, you might have - after tuition & fees, book & supplies - funds left for rent or food. If you borrow the maximum student loan you qualify for, you would get a larger refund which, again, would be used on rent & food - but NOT A CAR. The use of ANY student financial aid funds to purchase a car is prohibited - you can fix a car you already have, though.
In the long run, the less you borrow while in school the better off you will be - get a part-time job!
