I can understand your complaint, it is very difficult to get a good days sleep with the fan noise from the power point presentation. Next time try to get a seat in the back, and bring ear plugs.
IMO the 30 hours is insane, 10 hours of quality courses would have better results. A statement was made that the reason for increased hours, was to create more instructor jobs, continued education is a good thing, but a rush to complete hours is just nuts, most of the programs have last minute sign ups, and there is a last minute rush to fill the needed hours, so courses may be selected on a panic basis, rather then an intrest area.
