## Review, pt. 2: GMAT Official Guide 13th Edition w/ Integrated Reasoning

As we discussed in a post a couple days ago, GMAC has finally released the first new practice materials in anticipation of the Next Generation GMAT change on June 5th. We ran through some initial and general impressions, and we’re back to take a closer look. Here’s what we were told by our sources at GMAC:

Official Guide for GMAT Review, 13th Edition Fast Facts (from GMAC)

• 75 New Quant and 80 new Verbal Questions
• New Integrated Reasoning (IR) Chapter
• Online access code for 50 IR questions available as online practice
• None of the questions – new or old – are available in any other GMAC products
• Retail Price: \$42.95 (available in the Bell Curves Bookstore for \$29.95)

Looking more closely at the practice questions for the respective questions types, we’ve formulated a list of the new questions in the 13th Edition.

Sentence Correction

Passage 1 (Questions 1-4), Passages 4&5 (Questions 11-17), Passage 9 (Questions 37-41), Passage 12 (Questions 52-55), Passage 17 (Questions 84-86), Passage 22 (Questions 111–114)

Critical Reasoning

1, 3, 6, 8, 9, 11, 12, 17, 19, 22, 29, 33, 39, 49, 59, 65, 69, 74, 81, 86, 94, 100, 106, 114, 124

So what can we make of the latest edition of the Official Guide? Well, here’s our breakdown:

1) <20% New Questions – The new book has a little less than 20% new questions, which in the grand scheme of things isn’t an overwhelming number. That being said…

2) Quintessential GMAT – The new questions are retired GMAT questions, and as such are in a similar vein to what we’ve come to expect from GMAC.  But they are questions that mirror what you’d see on the GMAT, and are great practice for the test. Unfortunately, there’s not that many of them.

3) Integrated Reasoning is the Real Deal – For those of us who sat through one of the Next Gen GMAT testing windows in the past year, doing the practice questions reminded us of that experience, including the question interface and the nuances of the questions. While 50 doesn’t seem like a lot of questions, it is enough to give you a great feel for the different question formats and how to manage your time/strategies with them. It’s not enough to necessarily guarantee mastery, but hey, that’s what we’re here for!

4) Order of Difficulty – The questions have been roughly arranged in each section in increasing order of difficulty for the last couple OG editions, and this continues with OG13. While the Official Guide 12th Edition had quite a few questions that seemed misplaced given their apparent difficulty (either too easy or too hard for their respective location), OG13 fixes a great many of those misplaced questions. This means you can prepare even better with the knowledge that the questions are arranged in order of increasing difficulty.

Recommendations

If you’re taking the current GMAT…OG13 isn’t an imperative if you have OG12. You won’t need the IR, but you could benefit from the access to over 150 new questions. If you’re low on practice material, think of it as a source for a few more real GMAT questions.

If you’re taking Next Generation GMAT…OG13 is probably a must-have. Aside from the 15 IR questions that will come in the latest version of GMATPrep (due out 4/2/12…more on that soon), there’s no other source for officially licensed IR questions. Additionally, because of the refined order of difficulty and new questions, you’ll probably want to pick up a copy.
