Prior experience in the field: None
Gave a good overview about networks, covering many topics in the field.
Was a very easy course to complete/get a certificate.
No programming assignments to let you implement what you'd read about.
A lot of time in the lectures were spent just reading the slides/providing trivial explanations.
The quizzes tested stuff that was explicitly mentioned in the lectures - your hearing skills were tested, rather than your thinking skills.
The quizzes had the same questions on the second attempt - making it very easy to ace every quiz.
Add some programming assignments.
Make the quizzes worthwhile (or discard them).
A nice course if all you want is an introduction to networks (and a certificate), but you wouldn't want to tell others that you know anything in the field, since you yourself won't be sure!
