A lot seem to be in it for the sheepskin more than the knowledge per se. I took a college class where classmates explicitly advocated for the teacher to go easy on us and skip some stuff, it wouldn't matter, they just wanted their credits, did not want to have to work too hard for them (ie they wanted that class checked off their schedule, whether they learned anything or not). My reaction: What if you need to actually know that stuff (for a later class or your, oh, job)?

This did not make me popular. It just made me more of a nerdy social outcast.
