After signing up for summer classes in Mid April, I ordered this book. I didn't look at it until Sunday and noticed that it starts on page 15, then on after page 62, it goes to page 15-62 again. Unable to return as it is out of the "return window." There goes trying to be smart and ordering books away before you need them. Anyone want a useless $100 book that I can not seem to returned or exchanged?
