Ok.... I have another question... sorry to bother you all.
Im 17 and kinda dumb when it comes to basic geometry. Soooo does anyone have any website or somewhere i can go to because i cant figure out what it means to hold a book at 90 degree angle to eye and 45 degree angle to table. I know im not doing it right because my back hurts while i photoread and i get tired and almost MAKE myself stop.... maybe im not relaxing.... but i am sitting the right way. Alex, you previously said "prop the book up" ... the only problem is i dont know exactly how to do that because i dont know what a 90 degree angle to the eye is nor a 45 degree angle to the table.
