Exam and homework materials require thought and patience, but aren't crazy difficult or barely related to what is taught. Sam uses slides but also writes down derivations and examples, so it's important to follow along. Textbook is also useful, a couple formulas not in the slides can be found there.

E&M is an inherently difficult class. This professor used slides but used examples in solving problems that would eventually be seen in homework and exams. Read the book and attend lecture. Overall great prof for the class and gives good grades.

Not as easy as people make it out to be. Homework is easy. Quiz is average. Midterm is tough. Final was tough as well.

Sam is a great professor. He cares a lot about making sure that all of his students fully understand the material. His lectures mainly consist of him teaching from slides, and deriving equations on the slides with chalk on the blackboard. He's not the most engaging lecturer, but he is very responsive and helpful in office hours/outside of lectures.

Homework sets in this class were a mix of book problems and his problems that he created. They didn't take that long in comparison to other EE classes, so outside study is necessary to do well on his tests.

Exams were tough, but not ridiculously tough. If you spend enough time studying, you will find that the questions are very fair. Sam is a very generous grader and takes an improvement score into account. So if you do poorly on his quiz and midterm, but do very well on his final, he will account for that.

All in all, a great professor. One of the better professors in the EE department. I strongly recommend taking 101A with him.
