I took this class last year. Although it was nice to see undergraduates instructing the class, the lack of teaching experience really showed: the students were pretty rough around the edges in terms of their examples and explanations. About 2/3rds of classes ended early (at least this is better than heavily wasted time). This somewhat fits in with the unofficial caltech policy of "figuring out the finer details on your own".

That said, I thought the practical nature of the class was a refreshing switch from the heavily theoretical foundation of my other CS coursework experiences.
