It's important that the students understand the "course" of this class. I hand out a calendar showing what chapters we will lecture on and when; when tests and homework are due. In the first class, I go over when assignments are late, and the deduction for late assignments. After 7 days late, the student will receive no credit for that assignment. I go over this in class and give it to them in writing to review later. It's hard for them to remember everything said the first class.
