If you miss more than five discussion sections, you will have great difficulty doing the paper assignments, and the professor and AI may choose to deduct further points from your grade. You must have a medical excuse for absences if you do not expect to lose points. Athletic practice is not an excuse for repeated absence. Anything concerned with the class can be discussed privately with the AI or with Professor Wilk during office hours or by appointment. While it is usually best to talk with an AI first, any problem or issue can be discussed with Dr. Wilk directly.
Email is a good way to start.
These facts form the basis of our obligations to each other in the classroom situation. I consider it my obligation to listen carefully to your questions and answer them as well as possible given the need to finish the lecture. I will try again. Finally, I am obligated to be fair and explicit about grades, and about what to expect from the class. The other side of the story is your obligation as a student to me and to the other students in the class.
