This course says that it has all the material from the book, but the lessons skip around. For example, I think it’s skips from chapter 8 to chapter 11. It would make sense to me if the course just never got finished, but I wonder if there’s some explanation for why some of the material seems to be there and the rest isn’t. Also wondering if there’s a good course to skip to after finishing the seven or eight chapters that seem to basically be there.
