More students _per course_ than a MOOC cohort? -- doubt. If you add up all courses of a while discipline, edu portals still serve way more students.

In our department, about 20% reach a master. Sure that's more well rounded than a random bunch of courses, but it should be possible to even surpass the rigid choices of a lot of universities. I have no numbers for MOOCs at hand. If I had to guess: more like a gym: a lot of members, an order of magnitude less finishers?

I personally prefer the interaction on campus. But I dislike the outdated content of a lot of professors -- I'm not arguing about basics that are still relevant, I mean their /SoTA/ from 5-15y ago.
