I won't go into the specifics about what is contained in the course, since you can get that from this site. I will say that I found the homestudy course much more helpful than the book. Although the book has some good information, I was not able to use it to effectively learn Photoreading.
The advantage of the course is that you are led through various exercises to help reinforce the activities. It is also convenient for multiple listenings and each listening provides an added layer of depth that I missed on previous attempts.
There are induction sessions to help you get it into a more helpful state of mind. There are more concrete examples of what Paul is discussing.
Since you get the money-back guarantee, I would recommend giving it a shot.
