I might have missed it, but I'm not seeing much discussion on the followup[0] where he talks about moving to a more asynchronous course where it was possible to do enough extra credit assignments that students could bomb their exams and still get an A for the course.

The teacher seems very interested in student engagement with the material and understanding. Which I can only view as a positive.
