If you must be away get notes from one of your classmates. No private lectures will be given. Turn it in on the front table when you arrive. You will receive a 0 for not attempting the homework, a 1 for turning in homework that shows very little effort or thought, or a 2 for turning in homework that is complete. Notice that it doesn't have to be right.
Homework is practice.
Practice to make your test grades perfect. You can drop your lowest homework grade. Tests will be announced one week in advance. Your attendance is expected on test day at the time the test is given. An alternate test will be given only in extreme circumstances at the discretion of the professor.
