Sections
Lectures are supplemented by weekly, 1 to 2-hour sections led by the course’s teaching fellows (TFs). Different sections are offered for those less comfortable, those more comfortable, those somewhere in between, and those “least comfortable,” who might not feel ready for studies in STEM, let alone programming, but who are still eager (if nervous!) to dive in too. Attendance at sections is expected.
If you have a conflict with your assigned section, please email heads@cs50.harvard.edu ahead of your section time. Unless it is a sickness related conflict, you’d be expected to attend another section that week to make-up your attendance.

To be placed into a section, a form will be released in the first week of class that will ask about your time preferences and comfort level. Sections will begin on 2026-09-09T12:00:00-04:00, and a tentative list of the available section times can be found below.
