- Fridays, 10:40-11:40am
To summarize the changes: I no longer have office hours on Mondays. My Wednesday office hours are now in the afternoon. And I have added a Friday office hour in the afternoon. You may see a block layout of this information by going to my schedule.

9/19: (
 9/24) A reminder that there will be a QUIZ on Friday, September 26 during the last 20 minutes of class. The quiz will be 3 short questions. One of the questions will ask you to state a definition or theorem, one will be a computation, and one will be a proof. The proof will be very straight-forward if you've done the homework and remember the important results. The purpose of the quiz is to get you warmed up and ready for the first MIDTERM (see below). You will have 20 minutes to do the quiz.

9/28: Based on the results of last week's quiz, it appears that many of you have a long way to go to get ready for the midterm this Friday. I want to help you in this process as much as I can. Therefore I will be holding special office hours on Monday, September 29 after class, 10:40-11:40am and in the afternoon, 2:15-3:15pm. If you scored 11 (the median) or less on the quiz, I highly recommend that you come to one or both of these sessions to discuss your plans for passing the midterm and to clear up any conceptual difficulties you are still having.

11/21: VERY IMPORTANT UPDATE! Looking at the syllabus, I realized I had originally scheduled the last QUIZ for the Wednesday after Thanksgiving. This seems cruel and unusual given that I have also assigned four sections of HW to be due that week as well. Therefore I have postponed the quiz until the following week. The quiz will be on the last day of class, Wednesday, December 10. Please let me know if you have any questions. The quiz will cover Chapters 4 and 5, except sections 4.4 and 5.4.
