If you are a student in our school, go to the academic affairs office of your department. The teacher in the office will ask you to enter your student number password and log on to the educational administration network. Then he will print out your grades and stamp your official seal. That's what I did.

Some departments only give you a certificate from the head teacher, so if you need a certificate or phone number, go and say hello to the head teacher. He has the telephone number of the department.
