I do not want exactly to complain since the class is currently free and I am enjoying it quite a bit, but there is a lot of issues. The integration between the Youtube video and the quizz is poor, no official forum for the student, no lecture notes. Everything as a very beta feels to it.

On the contrary the platform for the ML class is of very high quality and the content more polished. I especially like the possibility to speed up the video lecture, having programming assignment, and how easy it is to submit them.
