Well, after I explain, I may be wrong

1) The book seemed to make sense.
2) It seemed as though the major points had to do with the sections of the book. Since it was a memory book it hit on different points like the 'Link System', 'Substituting Words', etc. After I PR'd and Superread/dipped, Those things made sense.
3) Previewing, PR'ing, Superread only took around an hour and a half to get the whole book.
It makes me want to PR more! Good Luck, it works
