Zoom Meetings

CS50 occasionally holds live lectures and sections that anyone on the internet is welcome to attend or watch, whether taking any of CS50’s courses or not!

For any Zoom meeting you attend, please take care to

• participate from a quiet office or similar space (and not from a bed, car, hammock, plane, or train), and
• participate with your camera turned on, using horizontal (not vertical) video.

If unable to accommodate these norms some week, please watch the live stream or recording at youtube.com/cs50 instead.

Schedule

Lectures

Whether you are a CS50x student, a CS50 AP student, a prospective student, a teacher, a parent, or a Harvard alum (or anyone else!), you are cordially invited to watch any or all of Fall 2023’s lectures online or even attend in person at Harvard University in Cambridge, Massachusetts, USA. These lectures will become part of CS50x 2024 on edX, so watching or attending now offers a bit of a preview.
