Watch our review on the GMAT OG 2022:

Manhattan Prep GMAT Strategy Guide Set

This is a set of 10 books or eight strategy guides that focuses on each section of the GMAT Syllabus. You have the option of buying these books in a bundle or individually. Apart from the books, you also get one-year access to practice tests and web material. These books will help you in strengthening your skillset to perform exemplary. You should note that the Verbal mock test question offered by Manhattan is simpler than what would be on the real test. The entire set costs approx—$ 150.

This is an excellent book if you want a solid foundation of concepts. You can get this book here.

Kaplan GMAT Prep Book

This book is highly rated by test-takers and reviewers to provide authentic GMAT prep. Practice questions for all concepts and question types are there with the detailed answer explanation. Also, there is one on one support offered by Kaplan faculty via Facebook. However, the latest updates are lacking. It includes six practice tests, with a 500+ online quiz bank that lets you customize your practice and select problems by difficulty and topics.

As compared to other GMAT prep books, this complete guide offers questions that are not too easy to solve. You can get this book here starting from $150.

PowerScore verbal trilogy Bible

This pack consists of three GMAT Verbal books – Critical reasoning, reading comprehension, and sentence correction. It consists of concept files and explanations with detailed methodology. One of the most significant disadvantages is that it does not consist of practice questions. Thus, if you want to learn the solid concepts of the verbal section, then this is the book for you. You can also get these books individually. On Amazon, this book has 4.7/5 stars.

Veritas Prep Complete GMAT Course

This set contains twelve dedicated guides and an in-depth overview of GMAT subjects. It also has more practice questions than Manhattan and includes unique and challenging practice questions.

However, the book lacks the answer key that provides for how to solve the problem. This book also has a mixed review. It’s quite similar to Manhattan GMAT prep, where it covers each GMAT topic in detail. However, as compared to Manhattan, the practice questions in this book are not only unique but challenging as well. Also, this book is more expensive than Manhattan. You can get this book at $250 here.

GMAT for dummies 2021

This book focuses heavily on test-taking strategies, including methods to help you work on your timing, the process of elimination, and guessing, and provides ways to tackle each question type.

It comes with seven online practice tests and flashcards. It is available on kindle and is a useful resource if you are just starting your preparation. However, you can use this book for reference only. You can get this book for $24.95 here.

Many GMAT takers are initially confused between choosing GMAT books or online preparation resources. In our experience, most go for GMAT books but eventually opt for GMAT online preparation courses. We talked to numerous GMAT takers to understand why they prefer Online preparation courses over GMAT books.

GMAT Books vs. GMAT Online Preparation Courses– Which is better?

GMAT Books vs. Online resources

Here are five reasons why GMAT online courses are better to prepare from than GMAT books:

  1. Less time to consume

If you are preparing from a data-driven online resource, you’ll need 7 hours for every 10-point improvement on the GMAT. Studying from books take 12 hours to do the same. Why? Look at the next point.

  1. Easier to focus

Audio-visual content is four times more interactive and hence effective. It is easier to focus, and therefore you require half as many revisions to reach a higher competency level. The result is that you learn more in less time.

Adam scored a dismal 490 and 530 in his first and second attempts. The reason for his failure – he studied from an old book in his first attempt and again used GMAT books to prepare for his second attempt. For his third attempt, he used e-GMAT’s interactive online preparation resource and scored a 700 on the GMAT.

  1. Online content is constantly updated

Online content always keeps updating according to changes and trends. Recently GMAC changed the GMAT format with a reduced number of questions and test duration. To adapt to the change, the online content of GMAT preparation updates within a day or two. However, you cannot expect the same to happen in the case of books. Books will only be updated when reprinted.

  1. GMAT is an online test

Since GMAT is an online test, it is better to train yourself on a computer during your preparation. If you prepare only from books, you’ll have to transition yourself from books to preparing on a computer, which will take up your precious preparation time. In turn, you can use this time to work on your GMAT Ability and Time Management.

Confused about your GMAT strategy? Attend our webinar on GMAT strategy and define your study plan for a high GMAT score.

  1. GMAT is a computer adaptive test

A computer adaptive test adapts itself according to the test taker’s performance. GMAT will throw different difficulty level questions at you during the test. The difficulty level will depend on how well you are doing during the test.

When you prepare using books, you miss this vital part: preparing yourself for the adaptive nature of the GMAT.
