I have yet to find a better book on Logic and Statistics. Believe me; I own GMAT books from several other companies. From the first page of the EZ Solutions Logic and Stats book, you will be guided through examples of how to solve the type of Logic and Statistics questions that will appear on the GMATPrep and Princeton Review's Practice GMAT Exams.

In my opinion, this book is perfect for anyone who wants to become knowledgeable in the areas of Logic and Statistics. Furthermore, this book assumes you have no knowledge of Logic and Statistics. Prior to this summer, I had not taken a Statistics course in 10 years.

During my undergraduate years, I was a Psychology and Classical Civilization major. Unfortunately, I was not a great student of Statistics. At times, I struggled with Probability, Venn Diagrams, and Permutation. Fortunately, I was strong enough in other areas of Statistics to pass three Statistics courses during my undergraduate studies. In my junior year, I decided to take Deductive Logic; unfortunately, I learned quickly that I did not have adequate Logic skills to pass the course, so I retook the course at another university that summer.

While I have not taken the GMAT, my opinion still has merit. This past summer, I ordered the Logic and Stats book before taking a non-graduate Business Statistics course through a top-tier business school. Without this book, I doubt I would have done as well in the Business Statistics course. Finally, I understand Probability, Venn Diagrams, and Permutation. I owe it all to EZ Solutions! If EZ Solutions had made its series of book while I was in college, I would have been a Math major.

I bought this (along with a couple of other supplemental EZ Solutions books for the GMAT) with high expectations, admittedly based on only the two reviews submitted thus far to Amazon.com.

Pros: The books do seem to be very comprehensive, and they provide plenty of practice questions for you to review the material you just reviewed in each section. The explanations are mostly adequate.

Cons: Like all other test prep books I've used, this one has its share of mistakes. On more than one occasion, a mistake in a problem was corrected only in the SOLUTION, not in the original problem. Still, it's not as egregious as Kaplan, for example, although the fact that the mistakes are hand-corrected with a pen is a little distracting.

The explanations are adequate, BUT they veer towards the downright technical, as the author often makes assumptions about one's grasp of math concepts that may not be warranted. Those of you only recently graduated from college, with algebra and calculus still fresh in your memory, might not find it a problem, but the author's explanations can be very confounding. For example: "Let E be a nonempty and non-equal subset of S, and let P(E) be the probability that is it possible but uncertain that it will occur." Errrr...come again? No clarification follows this sentence, so if you're math-challenged like I am you'll be left staring at the sentence for several minutes trying to wrap your brain around it.

In terms of overall clarity of explanations, I found Kaplan to be the best resource. The BIG problem with Kaplan, of course, is that their GMAT book is riddled with mistakes, so my suggestion is that you use Kaplan to learn/review the concepts, and use the EZ Solutions workbook (or the Official GMAT review book, or Kaplan's own online practice tests) as your dry runs.

Another thing I found off-putting about the books is the sheer expense, although when you compare it to the cost of, say, a live tutorial or class, it's obviously cheaper. Also, occasionally the language can be difficult to understand and can get in the way of answering the question properly, e.g., "How many people must be in a group in order to ensure that at least 2 people in the group have last names that begin with the same alphabet?" (Obviously, the sentence should end with 'letter,' not 'alphabet.'

Overall, the book is an okay resource. If you're looking for a quick refresher and are not starting from scratch, this may be a good option. If you're not necessarily math-oriented and want a book with more user-friendly explanations of even the more advanced math concepts, you're better off looking elsewhere.

The topics in this book are well organized and the content is easy to understand. I found the book to be especially comprehensive in its coverage of each topic. It is a very helpful book if you have been out of touch with math for some time. This book will definitely help to refresh the math skills you learned before, and the explanations/solutions to each math problem is very clear.

On comparison with other practice books, I found this book to be much better. If you are sincere about doing well on the GMAT, and diligent enough to work through each math problem, then this is the book to get. Upon completion of the problems in this book, you will feel well prepared and more confident about handling the questions on the GMAT. I would highly recommend getting this book if you want to get a higher score.

I highly recommend using this book for the Logic & Stats portion of GMAT. Despite having a quant background, I have struggled with some of the questions in GMAT on probability and permutation & combination areas. With the limited time available to prep for the test, I had to rely on a book which explained the concepts clearly and provided sufficient practice problems. This book did the trick and helped me tackle the problems in the Official Guide as well as those on the test confidently. Scored a 700.

In order to get a real GMAT prep - I would recommend you use the EZ Solutions series of 10 books, or whichever book(s) you think you need most help with. These books are very detailed oriented and cover everything on the GMAT math. First use the review modules to get the concepts and then use the workbooks for practice. Some of the most challenging math topics, such as basic arithmetic and number properties, algebraic concepts, complex word problems, logical reasoning problems, etc., are brilliantly explained in these books. Just because of the high price of the book, you can skip the math strategies book. However, the EZ basic workbook is a good refresher to get started and advanced workbook is a "must have" if you are aiming for a high score.

After doing all this, use the OG and you will see a dramatic difference in your scores. You don't even have to take any of those pricy courses. I followed this process and my scores have jumped from the 500-range to the 700-range. Good luck in your prep.

Some of the complex problems require logical reasoning as apposed to solving straight math and the math involved is not that hard but interpreting the logic into mathematical terms can be a problematic job because most of these problems are pretty abstract and often difficult to crack. The EZ GMAT logic and stats would be an excellent choice if you are struggling with logical reasoning.

I purchased this book along with the EZ Solutions' "Word Problem" book. The book is easy to follow and has lots of examples. I shows different methods of solving the same problem. The book is paperback and easy to carry around.
