10/14 Th  Midterm Exam During the midterm exam you must be present in our Zoom meeting with your live video on (no pictures), and your face must be visible (do not point the camera to show only your forehead!), for the entire duration of the exam taking. You cannot take the midterm exam with your phone only, as the Zoom app on it stops translation of video as soon as you switch to WeBWorK. Therefore, make sure to do the proper arrangements for the Midterm Exam! As soon as you are done with the exam, you are free to leave the Zoom meeting.
