Getting to Know the GMAT

Go to The GMAT to learn more about the GMAT

For additional information about the GMAT, read pages 7 to 13 in the Official Guide for GMAT Review (13th Edition)

Register an account on the MBA.com website to receive information regarding financial aid, recruiting events, and so on

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 (13th edition).  This downloadable Excel file is a convenient way to track your progress and identify weaknesses.
