I don't admit anything of the sort; you came up with the 2/3 figure. My best students are pretty much self-taught within the academic environment, which offers them a lot more than any series of MOOCs could. Maybe around 1/4 of my freshman students shouldn't be in university, and most of these leave during their first year. I'd be happy if admissions standards were increased, as it would be better for all concerned if individuals lacking the necessary ability and motivation didn't waste everyone's time as well as their own money. Once again, it is the responsibility of each potential student to determine whether they should accept a place at a university, not mine. As long as they're here, I'll give every student as much assistance as I can, but some of them can't or won't be helped.
