I saw one person years ago waste most of the last day of class cleaning decals on a very old German hand crank and it still didn't sew since she ran out of time to work on it. I hope she was paying a lot of attention during the 1 1/2 days of the lecture.
Don't get me wrong, he is still teaching on the last 1 1/2 days, just not a lot of straight lecturing. The last 1 1/2 days are to practice what you learned on the first day & a half. You also get to see and learn from the problems that the other students are having on their machines and that can be a lot.
