I haven’t signed up for any of the classes. I have watched many Grid episodes, I have a few of his books, and I have seen him speak in person. By the way, his wife can sing! Oh, and he claims to be the most published author of photo books. From the commercials I gather he has everybody who is anybody in the photo world creating course content for him. In that respect the classes are probably better than if you went to a local community college or university to study photography. That said, there is so much free content available, I don’t know if the paid stuff would be worth the extra cost.
