The OG13 has flaws, as did its predecessors. Why five stars, then? Because, hands down, this latest incarnation of the OG is still the one book to get, if you can only get one book to prepare for the GMAT with. There's simply no better all-in-one source of retired GMAT problems.Could the explanations be better? Sure.Could the GMAT folks have replaced more than just 1 in 6 problems from the OG12? Absolutely.Why did some repeated problems illogically jump the line backwards or forwards, given that both OG12 and OG13 are supposed to be in order of difficulty? Who knows.All that said, the OG is still THE primary religious text of the GMAT. Everything else--including all that we write in print or in byte--is commentary.The 158 new problems in OG13 all exude that sweet, ineffable air of GMAT-ness. Even if you're taking the GMAT before the changeover (on June 5), in your shoes I'd buy this book for those new problems alone. In the grand scheme, I'd consider that a good investment.If you're taking the GMAT on June 5 or after, you also need to prepare for the new Integrated Reasoning section. This book gives you access to 50 IR practice problems on a separate site online. Another reason to purchase.Now, on to the analysis...Analysis of the 13th Edition Official Guide(This analysis was originally published with additional content at [...])The 13th Edition of the Official Guide for GMAT Review has finally been released publicly. Here at Manhattan GMAT, we've done an initial analysis of the OG13 book.1. Not Radically DifferentOG13 contains 907 practice problems for the "main" part of the GMAT (Quant & Verbal). Of those 907 problems, only 17% are new.
I started GMAT Club - online MBA community; my GMAT score is 750 (49, 42), and here are my thoughts about this book:~~~ Strengths ~~~1. 907 real GMAT questions retired from past tests (158 new questions in this edition). The total has not changed2. Practice questions are organized by level of difficulty3. Practice questions follow actual GMAT test patterns (it's great to have one's ear trained, esp. in verbal)4. Contains a 100-question diagnostic test5. Overview of the Integrated Reasoning section (50 questions)~~~ Weaknesses ~~~1. Does not include any test-taking strategies2. Though it has a few short review sections for each area, they are weak and very unfriendly3. Questions are predominantly low to medium in difficulty which is often not representative of questions one encounters on the test4. There is an 83% overlap with the previous edition (12th edition). Compared to 66% overlap between OG 12 and OG 11~~~ Contents (number of questions per section)~~~1. Diagnostic Test - 100 questions2. Problem Solving - 230 questions3. Data Sufficiency - 174 questions4. Reading Comprehension - 139 questions5. Critical Reasoning - 124 questions6. Sentence Correction - 140 questions7. Integrated Reasoning - 50 questions (not included in the 907 count)~~~ What Questions Are New? ~~~* Problem Solving12, 13, 14, 15, 37, 49, 56, 57, 60, 61, 69, 71, 75, 77, 78, 79, 80, 81, 91, 92, 108, 110, 112, 113, 114, 117, 118, 119, 127, 128, 129, 137, 158, 163, 166, 170, 177, 178, 182, 183, 196, 198, 199, 218, 229.
Note that questions in this book are on average somewhat easier than ones found in The Official Guide for GMAT Review, 12th Edition. If you are looking for 700+ Verbal practice - look elsewhere.BUY THIS BOOK IF:1. You are studying using Manhattan GMAT books (there are only a few practice questions in the books and for additional practice,they refer to questions in the OG 12 and this book)2. You need more practice with average and low difficulty verbal questionsDO NOT BUY THIS BOOK IF:- You have OG 10 (there is quite a bit of overlap)- You have used or were planning to use power prep (previous version of the GMAT prep software has quite a bit of overlap too)- You have purchased paper GMAT tests from GMAC (overlap again)- You have not gone through OG 12 yetYes, this book is a cheap source of Real retired GMAT questions; (first being the Free GMATPrep software, second, The Official Guide), but the questions are easy and quite a bit dated. Bet the Main Official Guide first, go through 900 questions, and then decided if you really need more questions - most people don't. Also, it's not practicing thousands of questions that get your high score, rather it is a strong knowledge of basics, strategies, and control of the test.In terms of difference between 1st and 2nd editions - there are 75 new questions and it seems all sections got a bit of a refresh, so you will find about 25 new questions in CR, RC, and SC sections. No other changes have been made. If you own the first edition of this book - don't bother.
