That works pretty well for a full-time student, but two points... - If you're working/raising a kid/whatever, you don't necessarily have the time to drop into classes that might be full. There is likely a non-zero number of people who see their preferred section is full and don't move beyond that (people taking one-off classes, or slowly working through a professional certificate). - That's a lot of extra mental bandwidth for all involved. Yeah, it works, but life would be better if it wasn't the norm.
