@ccckid I’m at Cal. No you don’t have to take courses for your admitted major first term unless there is a foundation course that is required and you missed it because it wasn’t offered at your CC. I will slightly disagree with above poster because the more you can get done at a CC the less you have to scramble to do at the UC. Taking linear in summer is a great plan. So if you applied to another L&S major, and had all the CS pre-reqs done by summer you can start your fall term by switching majors - assuming CS accepts you. It is a capped major. Re switching, you do need to do it by end of first semester, so if you are missing required pre-reqs those need to be done by then, and as you are not in the major, you might find it hard getting into them.
