I also took the course, and I more or less agree with your assessment. However as someone who went to school a pretty long time ago and frankly never really learned how to study it was helpful. It reminded of one of those books you read where the author doesn't really say anything you didn't know, but puts the pieces together in a way you had not really thought about it. So I found it pretty worthwhile and I think if you are spending a lot of time trying to learn new things (i.e. foreign language, online courses, self study) it can be worthwhile, even if you are familiar with most of the techniques.
