However, it should be noted that the policies of each school may be different. Some schools may give graduates access to the educational administration system for a certain period of time, so that they can query the information they need, such as graduation certificates and transcripts. But even so, there is usually a time limit. After the time limit is exceeded, the school will cancel the login authority of the graduate educational administration system.
Therefore, if you are a graduate of Binhai College of Nankai University and want to continue to use the relevant functions of the educational administration system, I suggest you consult the academic affairs office of the school or relevant departments to understand their specific policies and regulations. They can give more accurate answers and guidance.
