I would not recommend skipping any base CS classes (61A/B/C, or 70). From what I have seen/heard, they are significantly more challenging than community college versions, and will better prepare you for upper-division classes than a CC course. Plus, I think they’re absolutely fantastic (though I might be biased as I’m a TA for 61A). Also, as far as I know, there are no CC courses that allow you to get out of 61A - even junior transfers have to take it.
The best courses to get out of are Math 1A and Math 1B (calc 1 and calc 2). If you’ve taken calculus before, I would recommend taking a Calc 2 course that gives credit for Math 1B. If not, take a Calc 1 course that gives credit for Math 1A. Make sure to check http://web2.assist.org/web-assist/welcome.do for transfer details - many CCs offer calc courses that don’t give 1A/1B credit.
I don’t think you can get out of R1A or R1B (reading-intensive general ed courses) with CC courses, so you’re probably better off doing an American Cultures course. Info on which courses at your CC apply for the AC requirement will be on ASSIST. A tip for avoiding tons of readings in R1A/R1B: choose your course/department wisely. I took Art History R1B and loved it - the readings were short and interesting. But English R1A/R1B is known for being reading-intensive.
I generally sleep 6 hours a night on weekdays, but on weekends, I’m in bed from 2 AM till noon 
Hope you enjoy 61A in Fall!
