Another option is that instead of buying the whole course, you buy only the book...then, if you get some success with it, you can prove to your parents that it actually works, and maybe then they'll buy the whole system for you.
The only problem is that less people are successful using the system with just the book than with the entire home-study course.
You can find the book here: http://www.learningstrategies.com/PhotoReading/Book.html
Hope that helps.
