  • Grading Policy:
    There will be 8 homework assignments, to be handed in in class on Fridays. Late homework will not be accepted; the lowest score will be dropped. There will also be two midterm exams, and a final exam. Make-up exams will not be given. The total score for the course will be based on the better of the following two: homework will account for 20%, as will each of the midterms and the final will contribute the remaining 40%. Or, homework 20%, the better of the two midterms 25% and the final 55%. This class will use the myUCLA gradebook facility.

    Requests for a regrading will only be considered within 14 calendar days of the due date of the original assignment, and no later than the day before the final. All such requests must be directed to the instructor; the TA is not allowed to make changes to grades.
