Best GMAT Prep Book

Manhattan Prep GMAT Strategy Guides

There are plenty of ways to prepare for the GMAT. Apps, books, flashcards, and similar tools. Web prep apps like Magoosh have also grown in prevalence over the years at the expense of prep books. But we're still fans of a good ole book. They're more affordable, personal, and just as effective. But finding the right one presents a challenge when there are countless available.

Some people want thorough subject review, and others just want hundreds of practice problems to work through.

We believe that the best GMAT prep book is one that provides a wide variety of practice opportunity alongside heavy subject review. Effective preparations for the GMAT require a balance of the two. It's really tough to find great subject review and practice questions all in one book so recommend the Manhattan Prep GMAT Strategy Guides. Yes, guides. A guide for each subject area of the test - especially useful if you've been out of school for some time.

How We Picked the Manhattan Prep GMAT Strategy Guides

Finding a prep book that prepares you for the GMAT is trickier than it sounds. Here's what we looked for when we compared different books:

  • Comprehensive Subject Review - Reviewing all the subject material that's on the GMAT is a must. There are a plenty of books out there that briefly graze over test topics, but they don't teach or reinforce the information well.
  • Excellent Practice Problems - Having practice problems that mirror what you'll see on test day is also at the top of our list. Some prep books sadly lack good practice problems (we're looking at you Kaplan) which leaves you ill prepared.
  • In-Depth Practice Problem Answers - It's even tougher to find in-depth, well written practice problem answers. You'd think publishers would prioritize this, but it's a key factor in separating the good from the bad. If you're spending the time and effort to learn, don't settle on having to hunt for answers on your own.
  • Full-Length Practice Exam - To properly prepare yourself, you'll need to take a timed practice exams. One exam should be taken as a diagnostic tool when you first start studying. Later practice exams should be used as a benchmark for your learning progress.

Comprehensive Subject Review

Here are the four sections of the GMT Exam to account for according to the Graduate Management Admission Council:

Analytical WritingMeasures a student's abilities in critical thinking and communicating ideas effectively.
Quantitative ReasoningAnalyzes data through problem solving and drawing conclusions using reasoning skills.
Verbal ReasoningMeasures a student's reading skills, comprehension of written materials, evaluation of arguments, and editing or writing.
Integrated ReasoningThis section measures a student's ability to analyze data and evaluate information shared in different formats.

The Strategy Guides give each of the three sections a further breakout:

  • Quantitative Reasoning
    • GMAT Roadmap
    • Number Properties
    • Fractions, Decimals, & Percents
    • Algebra
    • Word Problems
    • Geometry
  • Verbal Reasoning
    • Critical Reasoning
    • Reading Comprehension
    • Sentence Correction
  • Integrated Reasoning & Essays (Analytical Writing)

We like that the Strategy Guides cover the above major topics: With each topic being given an entire guide. The guides are arranged into chapters that start with content review and are followed by practice problem sets.

The guide for Fractions, Decimals, & Percents is broken down into Chapters of content review and practice questions.
