Making a decent course is a extremely hard task. And it requires a real (not based on inflated self-esteem) expertise.

Courses by Brian Harvey, Dan Grossman or Gregor Kiczales are real ones, while the crap could see on youtube, like Google's Python Course, is a disappointing waste of time.

Courses by Peter Norvig on Udacity are the gold standard.

Do not over-estimate your abilities. Good tutoring is hard. Just narrating copy-pasted stuff from the internet does not count as a course.

Same goes for books. On ought to grow up and become an expert first.
