Musumeci is a great in class lecturer. I could follow him much better than Corbin and he was funny and gave cool demos. His tests were also reasonable. The Mastering Physics is of course an overpriced piece of crap but the homework problems were still useful in preparing for his tests. His lecture notes are useful and pretty organized. He is the best physics professor I have had at UCLA. He honestly teaches better in big groups - I found him to be not that approachable during office hours.

His course is not particularly difficult until the second half of the material, for Diffraction and Interference. He knows what he is talking about, but for these sections specifically, it is hard to grasp what he is saying and his pictures suck.

Otherwise, his midterms are straightforward, but again, by the second half of the course, it's hard to know what formulas are relevant.
