普通高等学校招生全国统一考试
The National Higher Education Entrance Examination is not uniform across the country, but administered uniformly within each province of China or each direct-controlled municipality. The National Higher Education Entrance Examination is graded variously across the country. It is arranged at the end of the spring semester and secondary school graduates across the country take the examination simultaneously over a three-day period. Prior to 2003, the examination was held in July, but has since been moved to the month of June. This move was made in consideration of the adverse effects of hot weather on students living in southern China and possible flooding during the rainy season in July.
