I am going to be moving to San Fran soon?

I am going to be going to school out there. I am going to be getting finanical aid and look at scholerships and my parents will be paying the rest of my titution. I plan on living on campus with a meal plan. At the moment i have saved up about $20000 and plan on getting a part time job when I get out there. I just wanted to hear from some locals or students and if this is enough and any budget saving tips. Thanks any help would be great.
