@nprofile1q... Once in working to become certified as an instructor for a three-letter agency in a classified environment. Because I was a guest at that site, I didn't have any computer access so I had to make my demo class entirely unclassified (easy) and also without any computer aids (a little harder). I used a paper chart block and just wrote everything I needed out in markers and sketches and that helped me keep it to the important parts. Mine was overwhelmingly the favorite presentation.
