The student numbers of our school are sorted by grade, department, major and number.

For example, the student number of an economics college: 050 12 15030.

05 is the grade, 0 12 is the code of the School of Economics, 150 is the professional number, and 030 is the student number.

You ask the first few, depending on which grade and department, you are not sure!

I hope my answer is helpful to you!
