Orientation, Baseline Score, and GMAT Math

You’re now ready to begin your GMAT preparation.  In Part I of the Learning Guide, you will:

  • Familiarize yourself with the GMAT
  • Establish your baseline score
  • Learn general GMAT strategies
  • Learn all of the math content that the GMAT tests
  • Begin developing the proper mindset to take the GMAT with confidence

In order to follow this Learning Guide, you need the resources outlined on the Overview and Resources page.

IMPORTANT: This guide is arranged so that you cover all of the math topics first and then cover all of the verbal topics. You need not complete that learning tasks in that particular order. If, for example, you don't feel like studying math one day, feel free to study verbal topics. Just be sure to complete all of the learning tasks to ensure you've covered everything that the GMAT tests!   

Okay, let’s begin Part I.

Getting to Know the GMAT

Go to our GMAT page to learn more about the GMAT

Establishing your Baseline Score

Before you can establish your baseline GMAT score, you will need to familiarize yourself with Data Sufficiency questions.  Since Data Sufficiency questions are unique to the GMAT, you will have not seen this question type anywhere else. 

Go to the GMAT Prep Now’s Data Sufficiency Module and watch video #1, Introduction to Data Sufficiency

For additional information about Data Sufficiency questions, visit MBA.com

Download the GMATPrep software (the official GMAT practice software). GMATPrep contains two computer-adaptive tests (CATs) that you can take to assess your abilities and gauge your progress.   

Take GMATPrep test #1 

Note: This Learning Guide directs you to write each GMATPrep practice test up to three times.  Some students worry about taking a CAT multiple times.  To address this concern, please read the article, Taking the GMATPrep Tests Multiple Times.

If you haven’t already done so, download the GMAT Prep Now Improvement Chart for the Official Guide for GMAT Review (2017, 2016, or 2015 edition).  This downloadable Excel file is a convenient way to track your progress and identify weaknesses.
