This course is comically terrible. "Instructor" hasn't prepared at all for recording, he is often confused and doesn't know what he is doing most of the time. First half of course is him just reading text from official documentation, and that is kind of ok. But the other half looks like you are watching unexpected live improvisation of total amateur. Nothing works.. Error after error while I watch in terror as what else can go wrong. At one time there is even sound of somebody FLUSHING THE TOILET in the background that he did to not edit out (I kid you not, video "5. Message passing.mp4" at 03:47). But at least he made me laugh and I thank him for that.
Since this course is barely over 2 hours, don't expect to gain ultimate knowledge from this. But you can get some sense of just how low the bar is for making a decent Udemy course.
