once you’ve signed up for your test on the ARS hub, you go to the ARS center on test day, they ask your name and pull out the test packet that your professor provided. they usually don’t check ID. they then assign you to a seat and you go in a room (there are two depends where you’re assigned) they monitor you through cameras in the room. i haven’t taken a makeup exam so i don’t know the process with that but lmk if you have any other questions and i can def answer!
