The final exam will be held during finals week at the scheduled time. All homework is due back in class 3 weeks after being assigned (for example, if Homework 1 were to be assigned on January 22th, it would be due back on Feb.12th). Together, the three homework assignments will be worth 30% of your final grade. The two midterm exams and the final exam will each account for 20% of the grade.
