If this is an accredited course line, I don't understand how a subtraction of course hours can be assumed creditable ! ? Who's going to sign off on this excellerated classes?
One of the biggest problem I see is that everyone coming into a class aren't equally blessed much less knowledgable of all the aspects to be covered. One question per day could throw a course outline right out the window.
People will do just that just to grasp subject matter, or as a distraction to the course of study for that day...
Any one who's ever gone to class or has been in front of a class, should know this quite well... :grin:
