Homework Policy

Homework sets will be assigned for each class and are due before class on each Wednesday. Place the homework in the boxes just outside of 104 Bradley. Observe the section that you are in. Late homework will not be accepted. The assignments and announcements are posted on the Homework and events web page.

The homework scores not only count count towards your final grade and allow you to practice and refine your skills but, historically, those students who do the homework sets regularly fair better on the exams.


The course grade will be based upon the scores on the midterm exam, the final exam, and the homework.

Midterm exam 100 points
Final exam 150 points
100 points
Total 350 points

If you would like to have a tutor, please go to 301 Collis and fill out an application as early in the term as possible.


Students with disabilities who will be taking this course and may need disability-related classroom accommodations are encouraged to make an appointment to see their instructor as soon as possible.
