I wasn't at Princeton, but I remember blatant cheating going on and 'study groups' in CS classes that were mere passing around of completed code. (1997-2001)

I'd asked them what they expected would happen when they tried to get jobs or landed one. Like how do you fake work? They just said all jobs are group-based like their study group. (Keep in mind they were soliciting my code as their group was struggling to find solutions to assignments.)

The answer is a one of them works at a grocery store as a cashier, another one I saw now manages a bagel store (didn't know all of them). A waste of time, money, and effort to get a CS degree then just not be able to use it.
