Title: Almost all what you need
Review: This is an excelent material. Get this book, and buy another pack of practice tests from the web (plenty of them around) and you're all set. Just keep in mind that you need to have solid bases to benefit from this book and other practice tests; Nobody and nothing will teach you probability, algebra, grammar, etc... in a month. The author has a good sense of humor, which makes this book more readable and not so boring in such the painful task of studying for GMAT. Only drawback is that quantitative section problems in the real one are more difficult (better say, more time consuming) than the ones that come in ANY practice test. Always keep in mind that this is an ADAPTIVE test when studying, so, create your strategy for how much time to spend on the first 10-15 questions of each section.
