If you don't care about what grade you get you can probably still work at your own pace and just not get a good grade if you don't finish on time. And if you do care about what grade you get you are already pretending you're taking a college class.
That's what I plan to do and I'm assuming that the materials will remain available once the course is over like they were for the ML course, but there could be a better way to deal with left-behind students (which I believe are a big %) than making them circumvent a good chunk of the class experience (grades, email certificate), in particular I'm demotivated to do projects because instead of feeling rewarded for the work I did, I feel penalized for being late on some imposed schedule.
