Hi Barb - I'm taking the test for the first time on ProctorU on that same day! I have a friend who took it in October on ProctorU and he answered some of my questions about the whole process. Here's what he said;

Your camera and microphone will be on and the proctor will ask you to show them around the room and your desk - whether using a mirror or moving your laptop/webcam.

You will have to show a government-official photo ID.

Some advice my friend gave me, 1-2 days before the test give yourself a break because honestly if you don't already know it, you won't drastically change that in 48 hours.

All the best and good luck!
