When I took his class, there were only 10 students in the class. I really liked such a cozy classroom. Plus, we used his book as a textbook so that his lecture was perfectly easy to follow. His exam was not hard at all, either. He passed out sample exams before every exam, and we only need to study that. Yet, that doesn't mean that I didn't learn from him. I think that I learned a lot from him. He was available and very helpful both in class and outside of the classroom. I could tell that how much he enjoyed the material he was teaching. He was very charm, and I liked him not only as a person but also as a professor.
