The assignments were fun to do.
This is a math class (not a computer science or economics one.) I still wrote some groovy code in it though - I implemented the algorithms in code.
I only took the first 3.5 weeks (of the 7 week class) though. I caught the flu during week 4 and know i have too much going on the rest of the course to even think about catching up.
The lectures were clear with good inline exercises. The homeworks made you think and understand the material/apply it in new ways.
There was also some links where you could play the games against other students and discuss strategies.
The only thing I didn't like was the lack of feedback about homework. Once you get it wrong, knowing the right answer (and why) is important to learning.
