Exams and grades: There will be three in-class midterm exams, on Monday, October 9, Wednesday, November 8, and Wednesday, December 6. The homework and the three midterms will each contribute 25% to your course grade. Make-up exams for midterms will not be offered. Instead, a student may be excused from a midterm for a valid reason (e.g. illness or accident). In that case, the student's score for the missed midterm will be calculated based on the performance on the other midterm and the final.
