Message from Chemical Kim, First: When I review the test video and I don’t see you have set up the webcam so that I can see you, your work area, and your computer screen, you will get a zero grade. You CAN NOT use the nonremovable forward-facing webcam that came with your computer. You do need to have a webcam that detaches. Second: If you have a pen or pencil out, you will get a zero grade. You MUST use a whiteboard that is wiped clean at the end of the test. You will get a zero grade if I see a pen or pencil being used. Before you begin: YOUR CAMERA NEEDS TO BE A REMOVABLE WEBCAM IN THE CORRECT POSITION NO SCRAP PAPER ALLOWED! MUST USE WHITE BOARD! Show the camera the front and back of any printed handouts (only allowed to use the ones indicated). Show the camera the clean whiteboard Show the camera your calculator. If you’re using the calculator on your mobile (phone), it must be the “Desmos Test Mode” App. Select “Scientific Calculator” and Hit “Start Test” Show the calculator screen to the camera.
