Lectures are supplemented by weekly, 75-minute sections led by the course’s head teaching fellows. Sections are (smaller) opportunities to review the week’s material in more detail.

Attendance at sections is expected.


Below is a list of the dates and times of CS50’s sections this term. You should attend the section in which you enrolled on my.harvard. If you have a one-off conflict with your section, you may attend a different section for that week only.
