That UCB MET program in an engineering major + business is similar curriculum-wise as doing both majors. The difference is that students are direct-admitted to both majors (normally, business is competitive admission during one’s second year). Completing both majors means taking overload schedules averaging 20 credit units per semester instead of 15-16 credit units per semester.

Beware that some engineering employers see engineering applicants with substantial business courses as those who may be less interested in engineering itself, as opposed to using it as a fast track to management. This may be unfavorable when seeking engineering jobs. @HPuck35 can say more.
