Grading Policy:

Your course grade will be determined as follows: 25% from each mid-term exam, 30% from the final exam and 20% from homeworks.


Homeworks will be collected every Monday in class and some of them will be graded. There will be a 10 points completion grade for each homework set. Late homeworks will not be accepted except in extreme circumstances. Attendance and doing homework assignments are very important for your success in this class. Please turn in your late homework to TA's mailbox (see contact info for TA above) with a note explaning the reason for the late homework. TA may impose penalties for the late homeworks. If you disagree with the grading on an exam or homework, you must provide a written explanation, including your reasons for disagreeing, and resubmit the work for regrading within one week after the work is first returned to the class.

Make-up Policy:

There will be no make-up exams except in extreme circumstances (such as: death in immediate family, military obligation, etc.) at the discretion of the instructor. The instructor has to be informed IN ADVANCE by e-mail. You will be asked to provide proper documentation.


Class attendance is expected and I'll "spot check" attendance throughout the semester. I may deduct up to 5% of your grade if you miss more than two of those random checks.

Emergency Preparedness:

In the event of a major campus emergency, course requirements, deadlines and grading percentages are subject to changes that may be necessitated by a revised semester calendar or other circumstances beyond the instructor’s control. The primary way to get information about changes in this course is via this webpage and the course Blackboard page.
