Engineer The Course was excellent for 3 major reasons: -Mark is a gifted teacher that knows how to poll for absorption of material, knows the common stumbling points in the course and treads carefully, and breaks down complicated issues into easily digestible chunks of information. -The course materials are excellent and written in a conversational, easy to understand style. -The demonstration hardware Mark has on hand really helps those who learn better visually. In short, he addresses those that learn best by hearing, seeing, as well as reading. - Chris Marinelli
