Approval to take an exam at a different time must be made in advance and then only with a serious and compelling reason. Always keep a copy of your work. Sometimes papers get lost and sometimes papers are never turned in. A copy of your work will clarify the situation. You are responsible for retrieving and storing your graded assignments.
Office hours are individual or group meetings, depending on the number of people who show up.
If you have a personal matter to discuss privately, we can do that during office hours if no one else is in attendance. Otherwise you will need to make an appointment. You are expected to treat others in the class with respect and politeness. Students are invited and encouraged to think, question, disagree, and offer alternatives. Rudeness, however, will not be tolerated, and a disruptive student will be dropped from the course.
