I am on the last few classes. I am glad I purchased the lifetime membership as it has taken me a bit longer than 2-years! The course has been great, but requires a pretty significant investment of time. I fully plan on going back and reworking some of the class material in the months ahead. Price wise it was not cheap, but for me well worth the investment. My playing improved greatly. If you decide to buy the course get it on sale. Joe puts his course on sale a few times a year. His books are also very good.
How many hours a week practice do you think is needed to keep up?
