"That's kind of funny. I wonder how much negative feeback the course writers received on that one."
The IE piece was in recording your progress. So you could work on the course but the part that recorded the progress and granted credit didn't work. Once someone told you that, you had to go over the course again using IE but at least you could answer the questions more quickly.
Everyone got new systems out of the course though. The required system specs to take the course were higher than what we were using. We just had cheap Windows clients to get to our real development machines and performance wasn't really a necessity until the course.
