The staff do not seem to be active on the forums. This is especially important since quizzes contain mistakes and assignments are unclear.
Generally, little attention has been paid to detail:
* Mistake(s) in quizzes
* Lack of clear problem description and expectations in assignments
* Lack of communication from course staff
* Mistakes in the slides which are presented in the lectures
* Basic code formatting in the code samples on the slides/quizzes are missing.
That said, the lectures are pretty helpful and cover aspects of go (functional programming) that most go tutorials do not. If the problems are fixed, this would make a pretty decent go course.
