Go to: https://www.comptia.org/testing/testing-options/take-online-exam and run a system test using the same computer and network that you will use to take your exam.
The system test will take 5 to 10 minutes to complete. You will be prompted to take photos of yourself and your exam workspace. To prepare your exam workspace move all books and writing objects out of arm’s reach, unplug additional monitors and computers, and clear your walls of any writing (e.g., on whiteboards). You will also need an ID and phone (which must be set out of arm’s reach after check-in.)
To avoid delays and added stress during your testing appointment, complete the system test prior to the start of your exam appointment.
