You could get a personal loan to pay it off. I wouldn't recommend this (unless it is a lower interest rate than you CCs) since you have to make payments while you are in school.
Another option is to keep all of your receipts for the first month while you are in school. Appeal your financial aid award on the grounds that your monthly expenses, e.g., food, clothing, shelter, transportation, etc., are more than the school has allotted. Car payments and credit card payments are not considered necesities so they will only factor in stuff like auto insurance, books, cell phone (if no land line), etc. If they approve your appeal, they will increase your cost of attendance budget. Thus, you can seek more money from stafford loans or a private lender and will not have to pay it back while you are in school.
These are the only options that I'm aware of. I recommend making an appt w/ your school's financial aid office. They can go over w/ you what your options are and what are considered necesities for financial aid purposes.
