Or were the students he was given this year academically weaker, and just too pissed off with the whole COVID / remote learning / student debt / etc. situation (none of which was his fault) to put up with a weeder course (which OC always is) where the professor was too idealistic / stubborn / whatever to lower the standard "as far as it took"?
