This is very much a college by college thing. Where I did my CS degree, any student in the major was always going to be able to get their core courses on a proper schedule that allowed for on-time graduation. Sometimes that meant the college would add entire extra courses if there were more people needing something than expected. Did I get every elective (not all electives were taught every semester, some were only taught once every year or two, there was a large rotating selection - You had to take a few from different areas) that I was interested in? No, but I got most of them. ------- However, if you were a non-major looking to take some CS classes (beyond an intro one specifically intended for non-majors), you would have a tough time getting in. You were only allowed to register for those after all the students majoring in CS registered.
