Chongqing Yubei Jianhua Middle School divided 26 students with poor grades in Grade 3 of junior high school into a separate class. This move has aroused doubts among students and parents. However, according to Nie, a person in charge of the junior high school department, this is teaching by levels. Although this class is composed of underachievers from Grade 3, it is not a "class for underachievers" but a "basic class".
