A few of us Vex mentors and students are going to give this Stanford class a try.
Due to its popularity, they will be offering this class in two tracks:
the basic track - in which you watch lectures and answer basic quizzes. This is not the full course. But you will still learn all the basics of AI.
the advanced track - is the full class, which aspires to be of Stanford difficulty. You do homework assignments and take exams.
If you have a few advanced math courses under your belt it might be fun to try.
