USC doesn't care about your out of state tuition. UCLA is asian overload and an unnecesary expense for undergrad.
USCD is pretty fantastic, but.... if you like cool people and your education is important. I'd say check into Cal Poly Slo. It ranks higher than a lot of the UC's. Out of state ends up being like 12k the first year then around 4k each year after. Your education will be better and you will be around way more skiers.
USC has an awesome ski community as well, but again, not likely you will get in. If you want to go there, get a 4.0 your first year at a decent school and then transfer in. They love transfers.
