Every night after 24 o'clock. According to the announcement of Shaanxi Ministry of Education, in 2023, the dynamic query time of college entrance examination will be updated after 24: 00 every night. However, after confirming that the volunteer batch I applied for has been filed through the "Shaanxi Examination Enrollment" WeChat and Sina Weibo subscription number, I can check my file track and admission information. College entrance examination is a national unified examination for the enrollment of ordinary colleges and universities.
