When I was in the classroom I always understand the teacher but after school I often forget it.I don't understand myself why I like this and I don't want to forget what the teacher taught me all I want to remember what the teacher taught me I'll give you what teacher teach me to review and read the time close to two.Not want to fail again, I would like to pass friend like me, and when I read the book from my house to remember but at exam time I forget.
