Hi Hina,
I agree with vaibhav's suggestion. A full money back guarantee is a great incentive to try the program as you have nothing to lose. I would offer this word of additional advice though: If you do get the PhotoReading book or home study course, don't let yourself worry about how fast you learn the system and don't use your textbooks as your initial training material. Doing that would most likely cause you undue stress and tension because your agenda about the school work would interfere with your ability to relax and learn the PhotoReading system.
I hope that makes sense. From my own experience I can tell you that I really want to learn PhotoReading so I can tackle some extremely complex technical material (including schematics and engineering drawings) but I have deliberately stayed away from that type of material as I learn PhotoReading because I don't want to pressure myself too much and interfere with what should be a relaxed and non-stressed learning experience.
Just a thought from a newbie...
Good Luck!
Michael
