The National College Entrance Examination was held from June 7 to 9 in most of China. But around 100,000 quake-affected students in 40 counties in Sichuan and 17 cities, counties and urban districts in Gansu were granted a grace period considering the physical and psychological effects from the massive tremor.

The postponed exam will be held from July 3 to the 5th.
