The cs50 lectures stated in January 2015. Where can I access the videos? YouTube and iTunes U only have the 2014 edition.

  • Watch those lectures on edX

The current versions (Fall 2015) of the lecture videos are available on youtube at the following link: https://www.youtube.com/playlist?list=PLhQjrBD2T383Xfn0zECHrOTpfOSlptPAB However I don't know if those match the pset(s), etc. of what's currently available on the edX CS50 site.


If you enroll to this course here, you should be able to click the "Courseware" tab where you'll see all the video material.

  • This is CS50 2014

  • @Raul Rao, 2014 is the most recent version of the course. CS50 delivered live & in person at Harvard is a Fall semester course, so Fall 2014 was the last time it was recorded & distributed. Commented Apr 27, 2015 at 20:41
