Acknоwledgement оf Guidelines I understаnd thаt I must sit аt a table оr desk with bright overhead lighting and no backlighting, such as a bright window behind me. I understand that my eyes/face, keyboard, hands, monitor, and handwritten notes must be in view of the camera. See image below.  I understand that I must have handwritten notes when taking this exam, and without the required notes, I will face significant deductions in my exam grade.  I understand that if I choose not to use study notes, I must prepare a single page with the word "NOTES" written on it to comply with this guideline. If I haven't already, I can quickly get a sheet of paper to comply with this rule now.  I understand I cannot use any other resources (notes, devices, etc.) besides these handwritten notes.  I understand that I must keep my notes clearly visible to the camera at all times during the exam.  I understand that it should be clear throughout the exam that I am not using any other notes/devices--my eyes must be on the screen or clearly on the required handwritten notes only.   I understand that breaking exam guidelines may result in a zero or significant point deductions.  To receive credit for this exam, I agree that I understand and will follow these guidelines.
