I've taken the classes and I have found them to be very informative,easy to follow,questions/answer sessions..etc. The best part is..... you can watch the videos 24/7. The series covers the basics like the four or nine path,borders and binding.
Second series I think will cover the dreseden plate, apple core,rag quilt and sewing techniques. If your not satisfied you can request your money back. Hope this will help. :)
