You state that your parents are willing to pay the majority of the OOS UC tuition so how much is that? As a student, you can only take out a total of $27K of federal student loans for the 4 years ($5500 Freshman year, $6500 Sophomore year and $7500 Junior/Senior year), so your parents will pay around $60K/year for you to attend one of these schools?
Save your money, although the UC’s would love to have it and come to California for your Graduate degree.
