Shown both sides of your blank whiteboard. Completed the required room scan. Demonstrated your workspace, including your hands, keyboard, mouse, desk surface, area beneath your desk, your lap, and the surrounding testing environment. Verified that your testing space is free of unauthorized materials and electronic devices. You should also understand and agree to the following expectations throughout the examination: Your entire face must remain visible to the webcam at all times. You may not leave your testing area or move out of camera view until your exam has been submitted. You may not reposition your computer, webcam, chair, or secondary recording device after testing has begun. You may not talk, whisper, mouth words, read questions aloud, or interact with another person during the examination. No one may enter or remain in your testing environment during testing. You may not access notes, websites, AI tools, textbooks, additional browser windows, unauthorized electronic devices, or any other prohibited resources. Your secondary recording device must remain recording continuously and may not be paused, stopped, or adjusted until after your exam has been submitted.
