CS50x: Harvard's introduction to computer science
By Harvard University (CS50)
About this course
The CS50x 2026 page describes CS50 as Harvard University's introduction to the intellectual enterprises of computer science and the art of programming, for concentrators and non-concentrators alike, with or without prior programming experience, and says two thirds of CS50 students have never taken a computer science course. The page header links to OpenCourseWare and to a Donate page. It also asks whether you are interested in a verified certificate, a professional certificate, or transfer credit and accreditation, which are offered separately.
The page excerpt I read does not state fees: check the course page for any certificate fee.
