• (Oct 1) The quiz has been sent for photocopying. Coverage is 1.1 and 1.2. There are two questions. The one on 1.1 has four parts, one of which is a definition. It is actually one question divided into parts to make it easier to attack. The one on 1.2 is the kind of result which might be used later as a first step in solving some other question.
• (Oct 1) Due to popular demand the tutorial time has been changed to Friday at 9:30. The tutorial this week will be held on Friday, Oct 4.
• (Sep 9) I have posted the first homework assignment. Last year, I assigned problems from the textbook. To view my old assignment as well as my solutions consult last year's course page.

## Evaluation:

 Graded Assignments various dates (see above) 10% Quizzes October 4, November 8 10% Class Tests October 18, November 22 30% Final Exam Examination Period 50%

Alternate Grading Scheme: Assignments 10%, Quizzes 10%, Class Tests 50%, Final Exam 30%.
The scheme which gives the higher grade will be used in each case.

Note: There will be no makeups for missed uizzes or tests. If you miss one and provide a certificate indicating clearly that you were unable to write the test for reasons beyond your personal control, the weight of the test will be transferred to the final exam. Otherwise, the mark for the missed test will be 0.

The last date to drop the course without academic penalty is November 8. It is extremely important to realistically assess your course performance prior to this date.
