Professor Filipazzi teaches right out of the textbook, so if you miss a few lectures it's ok. There are weekly homework assignments that aren't too long. The majority of his tests are computation based, so they were all pretty easy (averages on midterms 1, 2, and the final were 88, 77, and 86.5, respectively). I never went to discussions and did fine. Overall, a very manageable class with a light workload, but also a class that will only give you a topical understanding of the subject. The textbook tries to teach in a "intuitive" way that's hard to follow if you've never learned this material before, and the professor pretty much follows the book to the dot.
