Professor Williams was above average. He is clear and is able to convey the concepts well. His voice is pretty bland, and his jokes take a few seconds to understand. I had Mess for 32A the quarter before, and Williams was a huge improvement. His exams are fair, though there was a tricky question on the first midterm. He drops the lowest two quizzes and the lower of two midterms. I think he curves a little, since my calculations told me I'd get a B+, and I ended up with an A- (not that I'm complaining), but that may be because the final had a pretty low average.
