Action is the difference between the book and the home study course. Every thing you need to know about PhotoReading is taught in the book. The course takes you though the information step by step and if you follow the instructions do the assignments you will have experience and experiments to see what learning PhotoReading is about in the course.
Just apply the five day test to 3 to 6 books and you'll learn PhotoReading. Takes about the same length of time (14 hours or a weekend) to learn from the book. So, grab a timer and record the time you spends with the books.
