Graduating students in a high school in Hengshui, North China's Hebei province attend an oath-taking motivational rally on Thursday, 100 days before the annual national college entrance examination, or gaokao. The school is famous for its motivational teaching methods and its impressive record of sending students to famous universities. But it has also been criticized for being too exam-oriented and has been dubbed the "assembly line of college students". [Photo/IC]
