The Registrar's Office publishes information on requirements and deadlines for thesis submission and graduation requirements. "The Form of the Ph.D. Dissertation," is a helpful guide to the physical and format requirements for the thesis, including paper and copying requirements, information about copyright, addresses of binderies, and more. You can check grades on line by using your Harvard PIN number.
Information about degree deadlines is available in the Graduate Office. Students need to pay attention to the Department's degree deadlines, which are often a few days before the registrar's deadlines to allow time for the Department to conduct its own degree approval vote.
