Exam policies
"Out of sequence exams" are offered for students observing religious holidays and students who need out of sequence exam as ordered from the accessible education office. See student handbook. If you have a lab conflict, it is usually possible to rearrange the lab for that exam time. We try to accommodate students with rehearsals, practice or regular classes, seminars or labs as well as possible but with a large number of requests this is not possible and would also compromise the integrity of the exam. In case of a qualifying conflict, contact Oliver knill@math.harvard.edu. Note that we can not offer make-up exam any other day. All requests have to arrive a week before the exam.
