What Should I Look for in a GMAT book?

Full-Length Practice Tests

When it comes to crushing the GMAT, there is one rule—practice! That means you need to find the GMAT prep book that has as many practice tests as possible. It’s okay if they are not all contained in your book, most good GMAT books give you access to plenty of online tests. The more exams you take, the better you’ll know the material and will improve your test-taking skills for exam day.

We ranked GMAT books with the most full-length practice tests higher in our review because we feel that this is an important feature. The good news is you have a choice. Kaplan, Manhattan Prep, and Princeton Review all give you access to six full-length tests.   Veritas Prep Complete GMAT Course Set include one, and the GMAT Official Guide 2021 did not offer any full-length tests, even though they have great practice questions. Kaplan seems to have the best explanations for the GMAT questions, so they get the nod here.

Plenty of Realistic Practice Questions

plenty of realistic practice questions

The same methodology applies to practice questions—the more, the better! However, the number of questions can’t be the only factor. Having realistic questions helps you acquaint yourself with the style of GMAT questions and practice the skills you need to do really well on the test. It is also important that the questions are at least as hard as the real GMAT, follow the same pattern, and have adaptive scoring.

The GMAT Official Guide 2021, Kaplan’s GMAT Prep Plus 2021, and Princeton Review’s GMAT Premium Prep 2021 all have over 1,000 practice questions. But, if you are looking for GMAT questions that are the most realistic, you have to go with the GMAT Official Guide 2021. The test questions come directly from the authors of the GMAT.

Comprehensive Answer Explanations

It doesn’t matter how many questions are included; the book is worthless if it doesn’t explain the answer in terms that you understand. All of the best GMAT prep books will give you the answer keys, but the best will have comprehensive, detailed explanations of why each answer is correct. Once you understand how the problems are solved, you will have the skills and strategies you need to crush the GMAT. A book gets bonus points if they also include tricks and tips to solve them. This helps you develop skills that are useful across all areas of the exam.

Kaplan’s GMAT Prep Plus 2021 stands out as the prep guide that offers the most complete and understandable answer explanations. GMAC’s GMAT Official Guide 2021 also does a great job in this area, providing detailed explanations for all of their practice questions.

Helpful Test-Tasking Strategies

Test Tasking Strategies

It will take more than subject knowledge to ace the GMAT. You need to build solid test-taking strategies that you can call on during the test.  Skills like time-management, quick answer elimination, dealing with stress, and good guessing will save you time and get you to the right answer quickly. The best GMAT prep books will also offer strategies tailored to your learning style and study habits. These tips and tricks to the GMAT must also include subject-specific advice to help you strengthen weaker areas.

Both Kaplan and Princeton Review have awesome sections (in the book and online) on test-taking tips and strategies. But the Princeton Review’s GMAT Premium Prep 2021 Edition is famous for its shortcut formulas and tricks to solve different questions, this prep book will save you valuable study time.
