This book suffers from a lack of explanatory content. Far, far too little attention is given to explaining things. If you're the type of person who likes to memorize then perhaps this book is for you. I got my bachelor's in math with a 3.9 gpa. I got a 790 on the math portion of the GRE. I have taken a few professionally administered IQ tests and consistently scored more than three standard deviations above the mean. Yet when I read this book I feel like an idiot. Not just kind of dumb, but someone who probably should put down the math and take up a new hobby. I'm not bad at statistics either, I have no problem reading papers or whatever. It is just that this book is so horrible. I am now looking for another book from which to learn.Also the book has low production values. The typesetting is poor, the binding is weak, and the numbering is occasionally confusing. One time the professor assigned the class a specific problem number and every single student did a different problem.
