Horrible audio. Many kotlin tutorials (in fact all of the ones I have listened to) are easier to understand, and I would say they do as good a job of explaining kotlin fundamentals. I found two errors in the video, and the section on for loops does show a working way to do them, but not the kotlin (idiomatic) way. As the first course I have paid for on coursera, it was a huge let down. The older free course (of course non for kotlin) were much better made. Very disappointed. Oh, one last thing, the quiz, said "Incorrect. Correct." for one question but did not give me the point! The question was which of these is capable of storing a null value: 1) var name: String? = "Bob" --OR-- 2) var name: String = "bob" --- the correct answer (1) gave me no points!! Very disappointed. A shame I could not give 0 stars.
