What is “much”? Is it nothing, is it something? You need to know the exact amount and then can plan from there. You can also get a job now and start saving.
If you provide your information (test scores, gpa etc) folks here will help you create a reasonable list but “the most prestigious school you can get into” is not an option. As everyone has mentioned, you cannot take out loans for it beyond the federal maximum, only your parents can and even if they were willing to do so (and it sounds as if they are not), it’s a terrible idea.
I agree, just because your parents make over $200K a year does NOT mean they can afford to pay a 60K plus price tag, even if they wanted to. And given that you are in CA, there is absolutely no reason they should. Depending on your stats you should have plenty of prestigious options to choose from, IF your parents will contribute something.
If however they will truly contribute zero, you need to recalibrate immediately and let folks here help steer you in the right direction of what options you may in fact have.
