Prof. Williams is a kind man who cares about his students. Although his lectures are indeed sort of boring - he tries to make up for it by a ton of interesting demonstrations.

The content of my class was very much the content in the book - which may or may not be a good thing, depending on the person.

His exams are fair in that they aren't IMPOSSIBLE. Prof. Williams seems to like to integrate a multitude of physical situations into a single problem in order to make it complicated. For example, although your homework will deal with friction, energy, springs, ramps, etc. individually, a likely exam problem will have all of that in one.

Overall, take his class - especially if you aren't bored easy.
