As I look at the Computer Science major from this page: http://www.admissions.uci.edu/applicants/transfer_prep/prep_ics.html
It looks like you’d be fine with C++/Java classes you’ve taken, but this then raises the question of do they mean 3 classes since UCI is on the quarter system? This would make sense considering the general sequence that can be found at a lot of CCs of Intro Programming > Object Oriented Programming > Data Structures/Algorithms, along with an Assembly class.
