Seek Alternative Transportation
Instead of driving to class and spending money on gas, parking passes and possible tickets, look into a local bus or subway system. If the system is run by your university, you'll probably be able to ride for free with a student ID. If a transportation system doesn't exist (or the existing one isn't safe or reliable), try to work out class schedules with friends and carpool. If you're close enough, walk or bike to class and get some much-needed exercise.
