BEIJING, June 6 -- A total of 9.42 million Chinese students will sit for the 2015 national college entrance exam that kicks off on Sunday.

The number has marked a tiny increase from that in 2014, which stood at 9.39 million, according to statistics from the Ministry of Education.

The Chinese government has motivated staff nationwide to escort the two-day exam, called Gaokao in China. Police were sent to roads and exam sites for students' security and drivers have been told not to whistle while passing schools and should give way to cars transporting examinee or test papers.
