I will have an extra 2:15 pm-3:15 pm office hour after the class on Dec. 7 (Tuesday)

Recall that I we have a scheduled 2:15 pm-3:15 pm office hour after the calls tomorrow (Dec. 2)

Note: During these office hours I will start answering questions at the end of the class and I will leave after students have stopped asking questions. So, if you have a question then come to class or be there at the start of the office hour.
