Chances at certain UCs

I’m a junior in HS in California, and I’ve been thinking a lot about where I’ll be applying next year. However, I do not want to “shoot too high”. So… please please please lend me some insight as to how I’m doing stats and standing wise. I have already done extensive research on my own on the websites of these colleges, but I think some insider advice would be super helpful. Thanks!
