This is CS50x.

Schedule

You are welcome to take CS50x at your own pace, so long as you submit nine problem sets and submit a final project no later than 31 December 2014.

To help keep you on track, allow us to propose a schedule of deadlines for you, if only for a bit of psychological pressure, but you do not have to submit by these dates. In fact, these proposed deadlines will be extended automatically as time passes. The only hard deadline is 31 December 2014, by which you must submit nine problem sets and a final project.
