Staff & Office Hours

Office Hours Calendar

Links to office hours will be available on Courseworks.

A note about office hours: the academic integrity policies outlined in mission apply to office hours as well, in particular as pertaining to possible discussions with other students. You are free to take written notes on anything the instructor or a TA says during office hours but we expect that students will not take written notes about problems away from collaborations/discussions with other students during office hours (or outside of office hours).

Office hours are not a place for regrade requests; as detailed in the course policies, those must be submitted in writing.
