Liu Tiemei's face flushed a bit upon hearing Xie Mengying's words.
Indeed, the reason why East River First High School could ensure a high college admission rate was related to its examination system.
The exams at East River First High School were strictly conducted according to the college entrance examination system. The questions were independently set by a specific organization, and each set of questions was entirely independent.
Liu Tiemei had also been assigned to set questions; during the phase from setting questions to the examination, she was not allowed to have any contact with her students.
Moreover, three sets of examination papers were issued simultaneously, and the set to be actually used was decided by drawing lots on the day of the exam, making it almost impossible for any questions to leak.
