If you are graduating in December, please make sure that you are not registered for the Spring 2012 semester so that you do not face unwanted tuition and fees charges. If you are registered and are not continuing in another program, cancel your registration by the January 13 deadline. International students should contact the Office of International Student and Scholar Services for more information. For more deadlines, see the Academic Calendar.
Please note also that the Graduate College Thesis Office will be closed from December 24 through January 2. Electronic theses and dissertations (ETDs) may be submitted to the Graduate College at any time during the winter break.
