Here, relations between students and professors are very casual and intimate. Sometimes, it seems impolite to me. But, I like discussion in the class. I think that it is a better way of teaching than the unilateral way. It was very nice to see how classes were going on.
Classes here are very different from ones in Japan.
Students here usually have a class in a small or medium classroom. Japanese students have a class in a very big classroom and we are not allowed to ask questions or give a opinion. I felt the relationship between professors and students are close. They talked to each other as if they were friends. It was surprising for me.
