> The reason is simple; a recorded video of a lecture is very different than a "college course". You typically don't have access to the instructor, class discussion, assignments, and evaluation of your work. Doesn't seem like a big deal. Most professors never have visitors during their office hours, most discussions I've attended have approximately zero unprompted participation. Also, OCW at least often has assignments. So really what you're missing is tests- not a $30,000 a year problem.
