I agree with what Crtang is saying about the blues course. I know there are parts where it gets too hard and am not sure what to do about it. The new rock course doesn't do that, we have learned our lesson and aren't repeating the mistake.
Crtang, if you could help us understand exactly where the problems are, we might be able to fix it for future students. If you can help me make a specific list of the places where you run into trouble, we can review them and edit the videos or reshoot them.
Is this the series you are referring to?
