Supersections are weekly review sessions led by the teaching fellows that supplement sections (otherwise known as "recitations" or "precepts" at other universities). These supersections were filmed in Science Center. Videos of Fall 2007's sections are not available, but videos of Fall 2009's sections are.

In order to accommodate students with different backgrounds, some problem sets are released in two editions: a standard edition intended for most students and a "Hacker Edition" intended for some students. Both editions essentially cover the same material. But the Hacker Edition typically presents that material from a more technical angle and poses more sophisticated questions.

This is CS50 OpenCourseware.

Computer Science 50 (otherwise known as CS50) is Harvard College's introductory course for majors and non-majors alike, a one-semester amalgam of courses generally known as CS1 and CS2 taught mostly in C.

Even if you are not a student at Harvard, you are welcome to "take" this course via cs50.tv by following along via the Internet. (The course's own website is at www.cs50.net.) Available at left are videos of lectures, sections (aka "recitations" or "precepts"), and seminars along with PDFs of all handouts. Also available at left are the course's problem sets and quizzes. If you have questions or would like to discuss the material with others, do join the course's Google Group.

If you're a teacher, you are welcome to adopt or adapt these materials for your own course, per the license.

If you'd like to take this course for real (on Harvard's campus or via the Internet) in order to receive feedback on work, grades, and a transcript, the course will next be offered through Harvard Extension School (as "Computer Science E-52") in Fall 2013. You can register online starting in August 2013.

Special thanks to Chris Thayer and Media & Technology Services for the course's videos and to Thomas Carriero '08 and Katie Fifer '08, Fall 2007's heads.
