The final exam is notcomprehensive. It will cover only material since the midterm exam.• homeworks: 40% ;• midterm exam: 30% ;• final exam: 30% ;Assignments can be accepted late occasionally within one week of the due day if you have a specialreason, but the grade will be reduced 25% for that assignment. Assignments CANNOT be acceptedone week after the due day.Course Outline: 1.
