This was a very well-designed class. Each problem set was lovingly crafted, and each problem helped me understand the material (there weren't any "filler" problems or long derivations where I learned nothing). The lectures were fantastic, and if you didn't like watching lectures, the lecture notes were great too. The class was a lot of work. Each set took one or two days, but there were only four sets in the class.
