The letter of admission for doctors is generally issued in June each year. According to Bo official website of University of Science and Technology Beijing, the admission will be announced in the society for a period of time, which also requires statistics, so the notice will be issued one month later. The enrollment of doctoral students needs to undergo strict screening and examination, and it takes a relatively long time to evaluate the applicant's academic background, research experience, scientific research results and other information. In addition, the school needs to coordinate the work of various departments. For example, colleges, tutors, graduate admissions offices, etc. , formulate specific enrollment plans and processes, so the distribution time is relatively late. Pay attention to the enrollment information of the school in advance, prepare relevant application materials in time, and prepare for doctoral application in advance.
