This was my first course with serious data gathering and manipulation. I found some of week 3 challenging, but overall enjoyed the learning.

Very good contents! But to be honest, the final course project is a bit too easy (I personally enjoyed it because it was not frustrating)...

Massively underrated - I appreciated this course and I learned a lot. I now find it baffling how taken-for-granted data tidying is.
