Normally, I spent 30min to do super reading and dipping.When I do that,I always feel it's not my unconscious mind notices me to dip some word or sentence,it's that part is interesting or the word was printed big and in red color.Now I think probably that the information I get from the book I Photo read was not from the whole PR system,It's from the word I dip and preview and post-view part.
I can't get to know the 70% of the book I PR.I don't want to give up since I want to be a master of PR and learn my major better.
