Your grades are available at CourseWorks. If you disagree with any homework or exam grades, submit your grievance email to the staff mailing list, documenting the merits of your case. The grader responsible will respond likewise via email. If you are still dissatisfied you may appeal in like manner to the instructor, who will only examine the email record of the dispute, and will respond in email. For a grade dispute to be considered, the written grievance must be submitted in writing within two weeks of when the respective assignment is returned.
