I think it's the first I follow a course where the teacher takes 5mn at each class to review and exemplify briefly what was done the last time. This stuff is quite easy as I already saw it in 6.042 for me, but it adds a level of clarity that is just amazing!If any teacher sees this comment: what this guy does is a GREAT idea, borrow it! We can allways spare 5mn in a 1--hour course.####[['teacher', 'Instructor', 'POS']]
