“Cal” means the UC Berkeley campus specifically. Is that what you meant?
If so, then transfer admissions for out-of-staters would be very competitive, as noted in Post #4. For 2016, the transfer acceptance rate for out-of-staters (not including internationals) at Berkeley was 6% (728 applicants, 46 admits).

Other campuses had higher acceptance rates for out-of-state transfer applicants (max was 37% at Davis). The UC system as a whole accepted 29%.
