Office: SAL 302
Office Hours (8/23/2021 - 12/3/2021): Mon/Tue/Wed/Thu 3:00pm - 4:00pm - Office hours will be held in Zoom meetings. I will have to limit the time for each student to be 15 minutes max to give other students a chance to get in. Zoom meeting has a waiting room and the wait list may be long. Therefore, there is always a possibility that by the time the office hour ends, you are still on the wait list. It may be best to e-mail your questions to me or post your questions to the class discussion forum. As promised in Lecture 1 of all my classes, I will answer every e-mail question within 24 hours (if the e-mail is a private e-mail, i.e., to me only and not posted to an online discussion forum).
