The games and mobile tracks have been deprecated and will not be available in CS50x 2021. If you wish to complete one of these tracks as part of CS50x 2020, you must do so prior to the date and time below. If you do not believe you will be able to complete the track by that time, you should pursue the web track instead.
Each track’s workload is equivalent to that of two problem sets, so plan to spend up to two weeks on your choice of tracks.
The learning curve for the mobile tracks is a bit higher, so for those tracks, be sure you can allocate plenty of time!

When to Do It
Though CS50x’s deadline has already been extended to 31 December 2021, this version of this problem set will only be accepted until the date and time above. Thereafter, you may only submit work from CS50x 2021, which will be released on 1 January 2021. Not sure you’ll finish the course by then?
