These exams are extremely stressful, and students overwhelmed by the pressure sometimes commit suicide, often dubbed Gaokao suicides.
It doesn't help that the essays of the top scorers, and sometimes those with a zero, are released to the public.
One teenager, however, obviously didn't care about his grade. In an essay on justice — or more accurately, 'sense of balance' — the teen wrote that he/she expected a zero. With China's intolerance for dissent however one has to wonder if the grader was too scared to give the teen a higher score.
