If you miss a class, it is your responsibility to complete the assignment, using your Glencoe textbook DVD, or sign out a text book from the library and complete the class work AND any homework coming from that classwork on your own time (material covered in most videos can be obtained also from the textbook).
You are responsible for all work done in class; an excused absence does not absolve you from that responsibility. Keep that in mind when missing classes for field trips, sports, personal reasons, etc.
