I've gone over 2 yrs in my adult life (during 3 separate occasions) without a car. Sometimes you just have to do what you have to do. Get a job at a fast food place (In-N-Out pays $10 an hr) so you can save for a car and have bus fare. Take the bus to class. I know it sucks, public transportation in so cal sucks but if you really want it than you have to compromise and do things you may not want to do.
