Hello everyone,
I wrote an exhaustive review of the 2016 Official Guide Bundle on Amazon. I hope you find it helpful! Special thanks to
dabral who helped me with many of the CAT statistics.

I am a Harvard grad and professional GMAT tutor with 15 years of experience, and am fairly obsessed with this test. I also take the GMAT at least once a year to stay up-to-date, including a recent score of 770 (48 V/47 Q). These books receive my strong recommendation because they provide a great source of real GMAT questions at a decent price.
One aspect of these books that you must understand is that they are not meant to teach you GMAT test-taking strategy. For that, look elsewhere (see product links below). However, they include some of the very best practice materials available, straight from the test-maker, and although the answer explanations are often convoluted, they are still useful in understanding how the GMAC thinks.
I'm not a big fan of classifying GMAT questions by category; each one is different, and many GMAT questions defy categorization. So I'll just say that the questions in these books are super-realistic. They are just like the questions on the real GMAT, because the book is written by the test-maker and uses actual, retired GMAT questions. Don't waste your time and money practicing on questions made by any other companies--these are merely inferior imitations of the real thing. If you must use other materials for test strategy, then that's fine, and in most cases necessary, but try your best to stick to official questions whenever possible.
Pro tip: You can take each of the 6 GMAT Prep CATs more than once, because the GMAT is an adaptive test (it adjusts the difficulty level of later questions based on your previous responses). There are about 4 to 16 times as many questions in the GMAC's question pool as there are in any given test, which means that every test you take will be different. Tests 1 and 2 draw from a (gigantic!) pool of about 1,500 questions, and tests 3, 4, 5, and 6 draw from a more modest pool of about 400 questions each. To re-take your free GMAT Prep tests, click "reset" in the lower-left hand corner of the GMAT Prep software window, but make sure to take screenshots of your previous test sessions beforehand--frequent screenshots are a good idea anyway because the software is prone to crashing and losing your data. For your screenshots, use either the "Print Screen" (Windows Key + PrtScn) button on a PC or (Shift + Command + 3) on a Mac.
It's important to remember that although these physical GMAT books are extremely helpful, the GMAT is still a computer-based test, which means that you should still do the majority of your work on a computer. For this reason, consider buying the Kindle versions of the guides, as well as making full use of the computer-based practice options available from the GMAC. Or, if you prefer to buy the physical books, then you can also use the access codes located in the sealed pouches in the back covers of the books to access a free Web-based version of the books, where you can try most of the questions in the books in an online format, and organize quizzes by question type / difficulty level (easy, medium, hard). You will also have to create a Wiley account, which is worth it because it allows you to travel without the physical books, so long as you have internet access and a computer.
Instead of giving you a paper and pencil, the GMAC also requires you to use a water-based maker and a laminated sheet like this one:
Manhattan GMAT Test Simulation Booklet w/ Marker I don't recommend always using the laminated sheet, because it's messy and harder to keep track of your notes that way. But it makes sense to at least use it a few times, just to get the feel of it before test day.
If you do run out of official GMAT Prep computer tests (the first two are free, and you can buy four more from GMAC), then I can recommend the
Manhattan GMAT CATs (computer adaptive tests). Just buy one book from the
Manhattan GMAT series, and it will give you access to all 6 online CATs: GMAT Sentence Correction (
Manhattan Prep GMAT Strategy Guides)
For free video explanations to all the math questions in these books, google "GMAT Quantum," or if you prefer to read your explanations, then just try google searching the first few lines of your question's text. I would also strongly recommend that you check out informative websites such as GMAT Club, Beat the GMAT, and Atlantic GMAT, and that you consider retaining the services of a qualified private tutor such as myself.
For those of you who are just getting started, here is the overall structure of the GMAT:
1) Analysis of an Argument Essay (AWA or Analytical Writing Assessment): 30 minutes, 1 question.
2) Integrated Reasoning (Multi-Source Reasoning, Table Analysis, Graphics Interpretation, Two Part Analysis): 30 minutes, 12 questions. Please note: unlike the Verbal and Quantitative sections, the IR section is not adaptive.
3) Optional 8-minute break
4) Quantitative Section (Problem Solving, Data Sufficiency): 75 minutes, 37 questions (2 minutes per question)
5) Optional 8-minute break
6) Verbal Section (Reading Comprehension, Critical Reasoning, Sentence Correction): 75 minutes, 41 questions (1.8 minutes per question)
Keep in mind that on the GMAT you cannot go back or skip any questions, and that the first 12-15 questions of the Verbal and Quantitative sections have the most impact on your score due to the adaptive scoring algorithm. A correct answer will yield a slightly harder question in most cases, and vice versa, and the GMAT will gradually determine your score as you go. The largest adjustments are made at the beginning of the test, which is why the first 1/3 of questions are so essential. Also, approximately 10 to 25% of the questions on the actual GMAT are experimental—you don’t know which ones they are, and they don’t count toward your score.

Princeton and Kaplan are OK for strategy too. I prefer Princeton Review’s GMAT guide (full disclosure: P.R. is my former employer) to Kaplan’s (in my humble opinion, a mediocre, corporate behemoth who somehow always manages to rank #1 on Amazon with lots of suspect 5-star reviews), but any effort to write an "all in one" guide to a test as complex as the GMAT is destined to be at least a partial failure. The Kaplan and Princeton guides can be helpful if you are a below-average scorer trying to obtain an above-average score without too much effort, but the perfectionists among us will be frustrated by their lack of depth and unrealistic practice questions.
