A good introduction course on UX Research and UX Design to get your feet wet.
After given an overview there are 2 sessions on UX Research and 2 on UX Design, each of them with a practical peer-reviewed exercise. The UX Research part I found a bit longwinded, this would have been better packed in one session in my opinion.
I enjoyed more the second part of the course on UX Design, good material on prototyping and sketching, and especially a very engaging assignment to elaborate on 10 ideas for a UX on a 10000-floor elevator in two iterations. These assignments alone are worth the course participation.
This course, however, is only a short introduction. It will not make you a professional UXer but you can get an idea if working on UX is something you, and if it is, take the other courses of this UX MicroMasters.
