I dont think its a matter of effort, or a matter of just PR the book. I PRed the book, went through it in a few sessions, followed the steps, and got a 56. That isn't a great grade, or anywhere close. On average I would get a 90 or higher in the class on assignments. A 56 is pretty far from that. I have spent time and effort trying the system, done the steps, done a few sessions for the book, but still failed. Things like this make it hard to go and try the system again really, because I can't risk dropping my average in the class. Sure, there is the option of PR a book for pleasure and see if I can get anything out of it, but it can't compare to having to read the book, not knowing what to expect on a test, and take the test with questions that you do not know were on there. Im pretty sure that if I had known the questions and what to expect on the test, I could have made a perfectly fine grade on it! But...in my school we dont get that benefit. It was a quotations test, all I knew was to look for quotes, important quotes, try and make connections and how people are so I could figure out a quote without actually knowing who had said it, but I only got about half of them right, and they were most likely the ones I had dipped straight into and read "This dude said this"
