“It really is a hidden gem. Amazon gets two thumbs up for selling these types of specialty books that most likely would not be given shelf space at Barnes and Noble to compete against McGraw Hill, Barron’s, Kaplan, Princeton Review, and all of the other publishers that have the publishing clout to get shelf space. Sometimes the most popular isn’t the best. McDonald’s overall revenue exceeds that of Peter Luger steak house, the best steakhouse in NYC, but it doesn’t mean you get a better meal there. Mike’s book is the Peter Luger of SAT math texts.”
