Well... i've waited for about 10 hours and really the book hasn't become much clearer to me... i must have done something wrong
PhotoRead again. If you have a difficult or new subject the easiest way is to PhotoRead it daily. I recommend this prior to lectures or classes. That way the class or lecture becomes part of your activation.
You did nothing wrong. Experiment some more. Like you did when you were learning to tie shoe laces.
