What are my chances of getting accepted to a UC as a transfer student?

Hello everyone,
I’m not sure how much W’s are factored in for admission, and I unfortunately have 4 Ws from my first 2 semesters. My overall GPA is a 3.5, but I’m confident I can raise it up to a 3.6 by the time a transfer. I have completed the IGETC and honors program at my school (RCC), and will have completed 84 units by the time I transfer. I have some EC, including a summer research program I did over at CSUSB and am the leader of a homeless drive organization over at my church. I applied as a chemical engineer to UCI, UCLA, UCB, and UCSD; what would be my chances of being admitted for each school? Which would be the better option to choose? Thank you for your time.

I am only answering the W part. The Ws will not be a factor.
