Quizzes will be given at the beginning of the class period. They will be short. Please be sure to arrive on time!

These in-class quizzes will be worth 10 points each. However only the largest eight quiz scores will count towards the course grade. **No make-up quizzes will be given.**

If the University closes on the day of a scheduled quiz and no exam is scheduled that week then the quiz will be given the next time the class meets. If the University closes on the day of a scheduled quiz and an exam is scheduled that week then the quiz will be cancelled.

**HOMEWORKS**

Below are the weekly homework assignments. These will not be
collected. However the material from the homework will appear on
the quizzes and exams. The dates given are when the material is
first scheduled to be tested on either an exam or a quiz. Quiz
material should be covered during the lectures and discussion
sections just before the quiz. You are responsible for the
material even if the University closes on the day of the
discussion section. It is a good idea to look over all material
* before * it is covered in the lectures.

These assignments are subject to changes announced either in class or on this webpage.
