Thanks KingOhm. (Interesting login name) I will follow up with that idea as well. I actually still have the modules from my years of apprenticeship from 1982 at what was then BCIT. I plan on using some of the material but obviously have time restraints as I will only be there for a month of which only half days of theory etc. Because of language barriers I would like to use stuff that is graphical in nature. There will be a translator but that can be slow. Has anyone any experience with the Mike Holt DVD stuff or any other DVD based theory that is graphical in nature?
