I was 30 minutes into my test today. The screen went black. The person said they lost the camera to log out and log back in. Did that, it wouldn't recognize my key strokes again. My co-worker emailed you already in regard to my issues yesterday and her issue today with talking the exam online. I would also like a full refund of todays online exam. I have scheduled to take the exam tomorrow at a testing center and paid the $100.00. Thank you.
