I believe the 3.91 GPA is unweighted, which means the UC GPA is probably higher with the honors and AP courses.
Also, of the 3 UC’s (UCB, UCI and UCR) that offer undergraduate business majors, only UCI (Merage School of Business) accepts freshman applicants. For UCB Haas and UCR business school, as state above, you would apply to another division, i.e., L&S, and subsiquently apply in your sophomore year as a junior in the business school.
