I realize that this may expose my grade to public scrutiny, and that the Division of Biological Sciences cannot be held responsible for exams which may be lost or stolen from this area. I understand that I may only pick up my own exam. If I do not sign this waiver, I understand that this exam will not be returned in class, but rather will be available no earlier than Friday, February 29th in the office of Sutara Tang in Room 1100C of Pacific Hall. Exams not picked up by the end of Winter Quarter will be discarded. Regrade requests (on exams taken in non-erasable pen only) must be accompanied by a cover letter stating exactly the issues to be looked at and must be turned in to Dr. Boulanger by Friday, March 7th.
