I have shown my blank scratch paper, front and back, to the camera. (If not, do it now). I understand that my exam session, including webcam and computer screen, will be recorded by Honorlock and reviewed by my instructor. (These recordings are only kept temporarily.) I understand that I may not use a calculator or external resources of any kind. I understand that violating these conditions will cause my exam score to be replaced with a 0.
