### General policies

All exams are closed books and without the use of any technology. Official policy at Harvard is that "out of sequence midterm exams" are only offered for students observing religious holidays. We sometimes can accommodate students who happen to have an academic conflict like lab, important sports event at the same time (game or tournament) or a concert or theater event. In case of a qualifying conflict, contact Oliver to see whether it is possible to arrange the exam earlier at the same day. Requests have to come at least a week before the exam.
