Calculus 2 or the permission of instructor.
AttendanceIt is imperative that students attend all classes. Students are responsible for all material covered in class, even if attendance is not checked or assignments collected.
ExamsThere will be three semester exams and a cumulative final exam. No makeup exam will be given unless the excuse for missing the scheduled exam is acceptable to the instructor. Any makeup exam must be taken before the next regularly scheduled exam. No exam grade will be dropped.
Assignments and Projects
There will be three assignments and three Matlab projects during the semester. There will be no makeup assignments. Assignments or projects turned in after their due date will receive an automatic reduction in grade. No assignment or project grade will be dropped.
