My college had no maximum on the number of credits you could earn by challenging the course. After learning Harry Lorayne's methods I tested out of two and one half years of college in eight months and graduated early.
We home school our eight children and we use this book with every one of them, to great success. I'm also the director of a learning center where we use this book as well.
Read the book, do the exercises, and use the tools every day.
A year or so later, I met Harry Lorayne during a show (he was a mental expert and I was a musician). I was absolutely astounded at what he did and decided that however he did it, I would do the same thing. I told Harry that, and he laughed and said, "Just buy any of my books--they all say the same thing."
I promptly bought ALL of his available books, found that he was correct, and returned all but one, "How to Develop a Super-power Memory." Yes, the method Harry teaches may seem to be a "kiddy way" or simplistic, but it REALLY works. My grades were "A"s thereafter. I remembered whatever I wanted, whenever I wanted, regardless of the detail.
If Harry Lorayne's methods don't work for you, it is ONLY because you did not apply them. Period. Do not for a moment think that "miraculous" results cannot spring from "simple" methods.
I also recommend anything Dr. Kenneth Higbee has written.
Get Lorayne's and Higbee's books; do what they say; you WILL be successful.
Peace.
I also reccomend The Memory Book by Harry Lorayne and Jerry Lucas. Its kind of like a big brother to this book and covers a llittle more info but does not focus specifically on school.
