I'm taking the Artificial Intelligence class and the Machine Learning class offered by Stanford. Both are online sources, and both are free. So far, they're not too bad, although I've clearly forgotten some probability stuff.
I'm taking the advanced track, with homework and exams. Unfortunately, I seem to still have my old problem of procrastination. Blegh.
I'm also really easily distracted. Was I this easily distracted back in college? o.O
