csu to cc to uc

Hello everyone currently I am a freshmen enrolled at CSULA as a computer science major. Previously at the beginning of the semester i decided that i wanted to transfer from a CSU into potentially UCI or UCLA. However, i found that taking that route wasnt the safest. Although i know i can get the required GPA, having to articulate which courses would transfer over was the part that really worries me. As such i have decided that after a semester here at CSULA i would like to transfer over to a CC for the winter session to guarantee my admissions at UC. I am deadset on attending one so i felt that this was the best option. Currently i am thinking of attending El Camino Compton for its low enrollment rate so ill be able to get classes easily, and i also have friends over there so its nice :). So some of my questions are how i should go about going to the CC, who should i go talk to , and will this decision put me behind on transferring to UC? Any and all help is greatly appreciated thank you !!!
