Agreed crab@, and I know its sounds harsh, but I'm pleased when they do. Unfortunately they usually take innocent people with them.
Anyway, mine were only suggestions, I think the system as it is needs a complete shake up. The Syllabus is there, maybe there should be an enforced time period to let people absorb the knowledge before they can move on? Perhaps a series of progress checks?
Like I said it will never happen, but what do you think?
