I returned this book after reading the first 10-pages. I bought this book with the expectation of finding the type of quality you can have from Barron's or Kaplan's as applied to the writing assessment section of the test. To my chagrin I found a 'primary school' type of guide that made emphasys in elementary aspects of grammar. This guide provides a number of fake-essays which do not even closely relate to the real GRE essay questions. It provides NO guidance or advice on how to develop an strategy to answer essays in an structured manner under time-limited conditions.In summary, Do not waste your time and money on this guide. Buy Barrons GRE guide which contains a concise yet thorough section on how to write the Argument and Issue essays of the GRE. If you need to polish up your grammar I would suggest to go to your nearest public library and get a quality grammar book.
