<p>At San Diego State, registration is scheduled on a rolling basis, in the following order: freshmen, seniors, juniors, sophomores. So the freshmen have first crack at all of the classes. And they constantly remind the students what courses they have to complete, both in their major and for required breadth curriculum. They really seem to want to get them out of there in 4. I would imagine the same holds true at the UC campuses. Remember, at a state supported school they lose money on every student. ;)</p>
