As sооn аs this cоmes up, even if you did one before stаrting the quiz, you must do а proper room scan: hold your laptop toward your desktop, spending a full count of 5 seconds pointing forward to where the laptop was sitting, then pointing down toward the working area of the desktop, then slowly turn it left, then slowly right, then back to the middle. If you have a desktop computer, you should have a full size mirror over your shoulder that shows your workspace, or a handheld mirror the size of a football or larger, and with it--face it toward your computer doing the same process as described above, pointed forward then slightly down toward the working area of the desktop, then slowly turn it left, then slowly right, back to the middle. Then select True, then resume your quiz. No room scan or improper room scan may lower your test grade.
