No. You can sometimes defer payment for a short time if you are unemployed or something. But there is no expiration on your loans and defaulting means the government would probably dock your paycheck from work.
Some states like Georgia(or maybe it was S. Carolina) have a program where if you get if make 90% grade point average in highschool, you can go to any publicly funded university in the state for free.
California State Universities have incredibly cheap tuition. You still have to pay your own housing, food, living expenses.
