**Math 220 Common Page**: A detailed syllabus and a list of practice problems are posted on the
common Math 220 page:

**Hand-in Homeworks**: There will be weekly hand-in homework assigmnents, which will be assigned week-by-week
and due on Fridays at the beginning of class. Late assignments will not be accepted. To allow for minor illnesses and other emergencies, the lowest 2 homework scores will be dropped.

**Exams and Grades**:
There will be a common final exam for all sections of Math 220. The Final
Exam (2.5 hours) will be held in December. The date of the final examination will be announced by the Registar later in the term. Attendance at the final examination is required, so be careful about making other committments (such as travel) before this date is confirmed.
Your course mark will be based on homework (10%), two midterms (20% each), and the final exam (50%). No make-up tests will be given for midterms. All examinations will be strictly closed-book: no formula sheets, calculators, or other aids will be allowed. The instructor reserves the right to revise or round off gradeds if circumstances
warrant. In order to make course grade standards consistent across
sections the raw final grade will be scaled.

**The Dates of Midterms**: The dates of the two 50-minute Term Exams are asfollows:

**Midterm Exam 1:** October 5 (Friday),

** Midterm Exam 2:** November 9 (Friday).

**Considerate Behavior and Cheating**: Talking in class is disruptive to
others trying to concentrate on the lecture. Violators may be asked to sit
separately or leave the class. Cheating on tests will not be tolerated. Any
cheating will immediately be reported to the head of the Mathematics
Department for disciplinary action. Cheaters are often caught and the usual
punishment is a 0 in the course, expulsion from the University for 1 year, no
transferability for courses taken at another institution while under
suspension and a notation on your transcript of the suspension due to
cheating. Finally, it is considered inappropriate in any course to bring
friends or other students not registered in the course into the lectures
without first obtaining permission of the instructor.
