I dо nоt hаve аnything in my eаrs, I am nоt wearing smart glasses and my taskbar is visible with no other apps open except my web browser and Honorlock. 1. Right now - turn your head towards your external camera and show me that you have nothing in either ear (like in the image above). If you have long hair that obstructs the view of your ears, tie it back for the duration of the exam. 2. Right now - if you are wearing glasses, please remove them and hold them up to the camera. Smart glasses are not permitted during the exam, you must replace them with standard glasses before continuing. 3. Make sure your taskbar is visible and close all unauthorized apps. To do this for Windows: right click on your taskbar > select taskbar settings > scroll down to taskbar behaviors > uncheck 'Automatically hide taskbar'. For macOS: click apple menu icon in top-left corner > open System Settings/Preferences > click Desktop & Dock > turn off 'Automatically hide and show the Dock'. By proceeding, you confirm that you did ALL of the above actions, and understand that if you did not, you will receive a 0 on the exam.
