My High School Life

I had studied in AA High School, in Shanghai, before my current high school. It is a High School in Shanghai. I had studied there for 2 years. Before I came here, I had never gone to a private school.
I think that my school life in that school was full of fun. Although I had some new challenges every day, I had been trying my best to meet them. I liked our school, because I am enjoying its atmosphere. I had gotten along well with my classmates. When I had some difficulties, they would also help me face them. I liked our school’s teachers and administration staff, especially my English teacher. He was very funny. He regarded students as his own children. At the same time, he was strict with us and strict in his work.

[Good work, but I was a little confused as to whether you were talking about your current school's experiences or those in the AA high school.]
