Query: Sales pitch to buy his other books

The tips given in the 1st few chapters are worth going over. The tests are of very little if any value to help the reader. I hate the fact that he tells you only so much about a subject and leads you only to a reference of his other books so you must buy everything he has written to understand what is in the book. If you are looking for a good "how to" on speed reading this isn't the book to get. all the info in the 1st few chapters can be found with a simple google search on how to speed read.
