3.0 GPA calculated by the CSU method means that you should be admitted to non-impacted majors at non-impacted campuses if you are a California resident. See https://secure.csumentor.edu/planning/high_school/cal_residents.asp .
The only bay area CSU campus that is not impacted is East Bay. Of its various majors, only nursing is impacted. See http://www.calstate.edu/sas/impactionsearch/ and http://www.calstate.edu/sas/impactioninfo.shtml . Of course, you can try for other campuses like San Francisco and San Jose.
