NO QUIZ GRADE if room scan is not done or not done correctly. THIS PROCESS IS REQUIRED BEFORE YOU GO TO THE NEXT QUESTION FOR YOU TO RECEIVE A GRADE ON THIS QUIZ, even if you did a room scan while starting, do a ‘slow and methodical’ scan now: Your full desktop area must be shown, and shown clearly. You must pick up your laptop and turn it around, without you in view, to clearly show the desktop area where you are working. It must be the same view of the space that you see while taking the quiz. To ensure you are simulating a secure testing environment, next complete a full 360, slow room scan of your testing location. You can do this by picking up your laptop/webcam and moving it around to show your desktop and then your whole testing area. Be certain when you turn your laptop or camera around, you tilt your computer downward so the camera can see the entire desk/table you’re sitting at. If not correctly or done too quickly to show the work area, you receive no grade for this quiz. If you use a desktop computer, you must have a ‘football size or larger’ (about the size of a laptop screen) handheld mirror and accomplish the same kind of full, slow demonstration of your desktop and surroundings. ONCE YOU COMPLETE THE PROCESS, CLICK True if you did the scan with a laptop, click False if you did it with a mirror. No quiz grade if you do no scan or for improper room scan that does not clearly and fully show your desktop.
