Grade

There will be weekly homework assignments, and two exams. Each exam will be given in class for 1 hour and 20 minutes. For the overall score, HW takes 20%, exam 1 takes 45% and exam 2 takes 35%. Exam 1 covers sections 4.4, 4.9, 11.1-11.7. Exam 2 covers 11.8, 11.9, 11.10, and 11.12. The final grade is determined according to the following scale:

A: 90-100

C: 70-79
D: 60-69
Fail: 0-59

The majority of exam problems will be similar to homework problems and examples given in the lectures. Exams are closed book. If your performance on the exams is very impressive, the percentage that your homework grades take may be lowered.
