So what’s the catch if you don’t graduate?
As a part-time prof I saw a lot of students start but not finish (some spectacularly so). AFAIK they had to pay back the tuition, which I assume most were incapable of.
BTW: most of the students who failed my classes did so simply because they didn’t do the work, not for lack of educational resources. I was incredibly helpful & lenient, and anyone with the slightest motivation had endless resources to acquire whatever information they needed to get the modest assignments done (I’d even make clear “if you have no idea what to do, just submit a file saying ‘I have no idea what to do’ and I’ll help you from there”) and the entire semester to do all the work ... yet 1/4 of students just didn’t do enough to achieve a pathetic 60% score.
I once gave failing grades to 3 entire classes (very small, but everyone nonetheless) in a row. Called the Dean each time, who said “give each what they deserve” and they did.
It wasn’t that they were denied or incapable (those were very few), it was that they _just_didn’t_do_the_work_.
