Comments about last class

I learned that how junior high school and junior high school students are at the last class. A teacher of Ueda junior high school came to our class and teached about junior high school. I learned a lot of things. He said that teachers work is mainly to change the students, the order is important in the teaching and so on. These were benefit for me.
I'm going to teach English at Ueda Junior High School, so I want to prepare for it hardly.
