In order to request a re-grading, you must submit a written request, explaining why you disagree with the grading, within one week after your exam is returned. You shall write the request on a separate piece of paper and hand it to me, along with your exam, during the office hours. Once a request is submitted, I will thoroughly re-grade every part of your exam. For arithmetic errors, please bring it to my attention immediately, either before/after sections or during the office hours.
