Midterm and final exams, in class and closed book will count equally in determining a preliminary grade. Home- work will be assigned each class day, discussed the next class day, collected the next class day and will increase or decrease the preliminary grade by at most one grade. For example, B+ and satisfactory homework = A-. Make-up exams will not be given. You must attend the final exam. The final exam will be from 8:45-11:00 on Thursday, November 19, 2009.
