Yes, it is possible to reschedule your GRE exam. If you need to change the date, time, or location of your exam, you can do so through your ETS account online or by contacting ETS customer service. To reschedule your exam online, log in to your ETS account and select the "Reschedule" option from the "My Tests" section. From there, you will be able to select a new date, time, and location for your exam. You will need to pay a rescheduling fee to confirm the change. If you are unable to reschedule your exam online or prefer to speak with a customer service representative, you can contact ETS customer service by phone or email. Be sure to have your registration number and other identifying information ready when you contact them. It is important to note that you must reschedule your exam at least four full days before your original exam date, and you may be required to pay additional fees to do so. Be sure to carefully review the rescheduling policy and fees before making any changes to your exam date.
