Problem sets: Problem sets will generally be posted here each Monday and due in class the following Monday.

Class participation: To satisfy the class participation requirement, each student must ask one mathematical question or make mathematical comment in class at least once before the midterm and at least once after the midterm. An acceptable question might be: "would you remind us what X means?" or "could you explain why you are using this notation?" I will do everything I can to help everyone satisfy the class participation requirement.
Exams and grades: There will be one in-class midterm, on Wednesday, March 14. Grades will be assigned based on the following formula: 10% class participation, 30% homework, plus either 20% midterm and 40% final exam, or else 60% final exam, whichever is higher. (Make-up exams for the midterm will not be offered.)
