UC GPA? http://rogerhub.com/gpa-calculator-uc/

UC GPA is a flat 4.0 I think

UCLA/UCB: Low Reach
USC/UCSD: High Match
UCI/UCD: Match

Include UCSC/UCR as a Low match/ Safety if you have none on your list.
Good luck

A low GPA gained in an academically poor school ruins your chances for most of those schools (eventhough your score is impressive, considering that!). Your best shot is with UCI.
