Dr.

As always Gary is succinct and quite clear in his directions. He points out software shortcuts and such that I had forgotten, and many that I was unaware of. He is always practical, and doesn’t try to snow his audience with jargon. I think this series of lectures/discussions are well worth the cost. Gary helps you get up to speed in a hurry. I refer back to his tutorials from time to time when I want to explore an area further, but initially was too busy to try out some maneuver. I have used a Mac since 1986, and am quite sophisticated in some aspects, and not so much in others.
