To me it does work!
i had a hard time in the first month, because I learned by the book ( Second edition in Portuguese-Brasil), so itīs harder.
But After that month I started having pretty good fun with it. Itīs worderfull to read a lot of things that before you hadnīt time but now you can read all, and more.
I Always had a problem in reading textbooks,magazines and book.
And after Photored it I can understand it very well.
If you buy the course, donīt give up by simple failures but learn with then.
I remenber the difficult to get the blip-page, a thing that is quite easy, but in the book wasnīt so clear about it.
But with the book(or the course) and the forum you can develop and solve the problems with the PRing.
Hope it helped
