Hello Hamzadarbar
Yes you can definitely learn PhotoReading using the book only. And as Photoread4me suggested above, anytime you have any doubts or queries, please feel free to post them on this forum. This forum has lot of knowledgeable and helpful people who are more than willing to help others.
Further, I would like you to be more specific when you say "I dont see any results". In other words, what results were you expecting? What are all the books that you have PhotoRead? Please fill in the details and people will be able to help you out better.
God Bless You.
Kind regards
Vaibhav Sharma
