Course News: I will give Review Sessions on Friday December 14, 2:30-3:30, as well as Monday December 17, 3-4. Rooms TBA. If you don't hear about the room, come to Farshid's office, 1118 LGRT. FRIDAY DEC 14 Review @ 2:30 in 1634 LGRT. The room is locked so if I'm a few minutes late, please wait quietly.

The Final Exam is scheduled for Wednesday December 19, 1:30-3:30 pm. Farshid's section (Section 4) is in GSMN 51, Goessman Lab Addition, 51. Anne Schwartz's section was scheduled for LGRC A 301 but has been moved to GSMN 51, same room as Farshid's section.. Rob Kusnder's section will take the exam in GSMN 20. Goessman 51 and 20 are in the basement of the chemistry building adjacent to Lederle. From the basement, there is a tunnel connecting them. Turn right, 51 is at the end on the left, for 20 you have to go around a couple of more corners if you go that way. Good luck studying, see you at the exam.

Here is the Sample Final Exam. There is also a Brief List of Topics prepared by Prof. Dan Yasaki. Feel free to consult Dan Yasaki's web page for Math 235 in Spring 2007 which has last year's sample final with solutions.
Here are Sample Midterm Questions Feel free also to consult last year's sample midterm: it can be found on Professor Yasaki's webpage -- together with solutions!! Also you will notice that there is a large overlap between last year's sample exam and this year's.

2) I might post some FARSHID'S COURSE NOTES to mywebsite.

Quizzes: Quizzes may be given on occasion. they may or may not be announced ahead of time. They will consist of one or two very simple questions. Absolutely no make-up quizzes will be given. Your lowest quiz grade will be dropped when computing your quiz average score.

Homework: Homework will be posted on The Homework Page and collected regularly at the beginning of lecture, usually on Thursdays. Late homework will not be accepted and the lowest homework grade will be dropped. Be sure to read and follow the homework rules.

Attendance: Attendance in mind as well as body is required. I consider attendance AND participation important ingredients for your success in the course. Frequent absences will be reflected in your grade.

Extra Credit: Some extra credit problems will be included in the homework assignments, or given during class.  The number of points for each problem will vary, as will the difficulty of the problem. The student with the most points at the end of the semester wins a fabulous prize. You may hand in Extra Credit solutions at any time throughout the term, until the Final Exam.
