This class is hard but you do learn a lot. Williams knows his stuff forwards and backwards...I swear this dude dreams E&M, and he can answer almost any question people come up with with literally 0 hand waving. He is incredibly clear (although a bit stern) and runs a tight, manageable class. If you are an EE looking to learn about EM, take this class. If you are looking for an easy tech breadth class, do not take this.

clear and organized lectures.
Midterm was similar to hw, final was very similar to the type of questions in practice final he posted online.

Prof. Williams' EE101 is challenging but rewarding. His lectures are well prepared and he (naturally) speaks perfect English. There are weekly homework assignments that reflect the material in lecture nicely. His tests and quiz are probably easier than the homework assignments. Prof. Williams is the type who doesn't hand out answers, and would prefer to walk you through a problem instead. I really have no complaints for this class whatsoever.

If you want an easy A in 101, take Ozcan. If you really want to learn a lot about E&M, take Williams. Williams is probably the best professor I've had here at UCLA. Like the previous person said, he does come across as a little serious, but he is definitely the most articulate and concise lecturer I have known. His pacing is good, his explanations are excellent, his homework is challenging (but in a good way), and his tests are fair. To me, they felt comparatively easy given how well prepared I felt from homework and lectures. He was also a fairly generous grader (though not as generous as Ozcan). I would highly recommend Williams for 101!

Professor Williams is definitely THE PROFESSOR that you should take EE101 with. At first he seems a little serious, but later on you can tell that he is a pretty easy going person. Furthermore, he always ask students if they have any questions, on top of that, he also seems very passionate about answering some of those questions. Overall the course is thoroughly taught and his lecture notes are also well organized.
