UC Cosmos

What are the odds of getting into cosmos. I have a 3.85 uc capped gpa and 4.2 weighted (not uc) gpa. I’ve gotten a b and c’s in science classes and a and b’s in math. If I have decent to pretty good essays and recommendations what are my odds? Also is it better to submit earlier, do sat scores matter, and should I go to ucsd campus if I want to go to college there? Thank you
