I will say that Dylan is fine, but his lectures are kinda sleeper, not very entertaining. The thing I don't like is that the quizzes and exams are very hard. And the assignments are very difficult even he allows students to work together. This class was a commonly known easy class, but Dylan made it very difficult until a point I think it is extra.
For his first time teaching this class he did a great job explaining the material and making himself accessible throughout the quarter. I could tell that he really valued feedback and adjusted the class accordingly. My number 1 tip is to review the lecture slides and do the study guides and then you'll be all set.
