Great guy, interesting lectures. He gives great examples, but fails in explaining the core concepts the examples are illustrating. Hard paper grader. Expects a lot out of students with little/ambiguous instructions. Mutiple choice part of exams are easy, but he grades hard on the short/answer essay portion

Afifi is a nice guy with really interesting lectures. His class SEEMS really chill at first. But, he grades papers really hard-- i worked my ass off and he gave me a B-! The midterm is mostly multp. choice, one "short answer" which is more like write about everything we learned so far. cool guy, but u gotta put in lots of work even for a B!
