First of all: Thanks Udacity Team and especially Sebastian for this awesome class CS373. It was a real pleasure to take this class and I had lots of fun and I learned A LOT in just 7 weeks. Chapeau!
As many class mates think the final exam is not challenging at all, why not get back to ai-class setup?
In ai-class we had a basic- and an advanced track. The Basic-Track just requires you doing the quizzes and after the class is over, you get a statement of accomplishment with your score for the track you have chosen.
The Advanced-Track is more challenging: You have to do the homeworks and the score in your homeworks + midterm exam + a final exam. To get 100%, you need all homework 100% (you can drop the worst) and 100% in midterm and final exam.
What do you think?
