Your grade will be based on the following percentage scale:

A+ = 97-100 C+ = 77-79
A = 94-97 C = 73-76
A- = 90-93 C- = 70-72
B+ = 87-89 D+ = 67-69
B = 83-86 D = 63-6
B- = 80-82 D- = 60-62

60% of your grade will be determined by 2 take home tests.
40% of your grade will be determined by 7 closed book quizzes.

Suggested problem sets will be handed out at each

Course Policies

It is very important that you attend all classes. In the event that you should
have to miss a session, you will be responsible for getting the notes from
another person in the class and to be ready to take the quiz and hand in
