You could always start off in the California State University or the community college system. Don’t rule that out. Your parents should not be ashamed of you for not getting into UC on your first try, if it happens that you don’t. At least you will have learned something if you don’t get in, and you will study harder in college if you want to keep the dream of transferring to one of the UCs alive.

In the mean time, knock the ball out of the park with your senior grades. You will need to, especially in the first semester. If you ever want to transfer to a UC from another college, they will probably look at your high school transcript as well, so make sure you keep good grades throughout your entire senior year.
