On exam day:
We recommend logging into your account 30 minutes early to start the check-in process and to allow for any troubleshooting. If you are more than 15 minutes late after your scheduled exam time you will be unable to begin your exam and are unlikely to receive a refund.

Click on the “View Appointment Details” button under "Future GMAT Online Exams"
Click on the link for your scheduled exam on your Dashboard
Click “Begin Exam” and follow the on-screen prompts to complete the check-in process
Once you have completed the check-in process you will be contacted by a Proctor to begin your exam.
