Title: Useless if you are aiming for a high score
Review: The author of this book is trying to help you more at guessing than to help you understand the matter. Let me start with the verbal section. Some problems in the practice tests do not make sense at all. Reading the explanation I am surprised to find out that some words have meanings that cannot be found in any dictionary.The math is horrible. In general the graphs require great skill at guessing where the values fall or otherwise you will not get correct numbers. (Practice test 2 questions 14 and 15) There are graphs that are wrong. (Practice test 2 questions 20 and 21). The problems are solved and explained in such a manner that shows you the workarounds if you have no idea how to solve the problem. The essential theory behind the problem that is being actually tested is not explained.I would not recommend this book if you want to get an excellent score. Rather it would be good for someone who wants to get the scores from low to an acceptable level.
Is the review positive or negative?
