Haha...funny thing, on exam days you notice the classroom is always full, but not on typical lecture days (maybe 1/2 the class is there). Attendance counts in this class but because it's an ethics course the professor lets you fill out an attendance sheet on the last day of class. It's implied that since it's an ethics course you're supposed to have integrity and be truthful on those, but I wonder if that really happens.
EDIT: class is about 200 people I think.
