This book is thin compared to other books available in the market. I just took 2 hours to finish the book as the methods taught are straightforward and easy to apply. Moreever, not all the materials need to be read.
The first 2 chapters talks about some achievements of the pioneer in speed reading, etc. The first few pages of every chapter typically spell out the problems faced in reading and the gist comes in in the middle of the chapter. My advice for readers is to skip the aboves and go straight into the methods.
