According to http://www.universityofcalifornia.edu/infocenter/freshman-admissions-summary , 2015 applicants with UC GPA in the 3.80 to 4.19 range were admitted at these rates:
12% UCB
14% UCLA
39% UCSD
49% UCSB
52% UCD
57% UCI
83% UCSC

However, the major or division applied to can make a significant different in admission selectivity at some campuses. Applicants to popular majors should assume that their chances are worse than what overall school admit rates may predict.
