Responsibilities:
It is important to realize that, though the instructor will present the material as coherently, logically and clearly as possible and that he shall be amply available for consultation, the prime responsibility for learning the material rests with the student. To this end, the student is advised to spend the appropriate time per week on the course, starting from the first week. A lesser effort shall likely lead to disappointment.
Classes start on time. Arriving late is disruptive to the class. Attendance is expected. Lack of attendance and/or failing to hand in more than 15% of the assigned work without a substantive reason may result in the student being asked to withdraw from the course.
Assignment Grading Policy:
Assignments will be given and collected at the beginning of the class on the date specified at the time of assignment. All assignments will be corrected, graded.
Late assignments will not be accepted and will receive a mark of 0. Solutions to the assignments will be distributed
Interactions of students on the concepts involved in the homework assignments are often helpful and encouraged, but each student works out his/her own solutions. Please acknowledge any substantial assistance that you may have received from a fellow student. Outright copying is not tolerated for all parties.
