Home work: Home work will be assigned weekly, and will be collected on Wednesdays. You are expected to complete all the assigned problems, although only selected problems will be graded. Late home work will NOT be accepted. I will make no exceptions for this rule. In compensation, the worst 2 homework grades will be dropped.

Quizzes: Quizzes will be given in class throughout the semester, normally on Fridays. A quiz usually takes 10-15 minutes. Notes, books, cell phones, calculators or similar items are not allowed in quizzes. Quizzes will be graded. There will be no make-up or conflict quizzes. I will make no exceptions for this rule so please do not ask for it. In compensation, the worst 2 quiz grades will be dropped.

Attendance and Class Participation: Full class attendance is required, therefore will be checked every class. If you miss more than 5 classes without valid reasons, it will be taken into account for your final grades.

Lecture Notes: Available on ANGEL for registered students.
