Very interesting but a bit tough and time consuming with a lot of work on your own... but that's probably how you develop real life hacking behavior!

Assignment difficulty is good and practical, however, I took quite a while to understand the raw data structure and the purpose of the assignment.

A very interesting and unique course, for the kind of things it helps to learn are often ignored. It brings the breadth of the theme forward.
