If you want to change the grade, you can only change the account of the teaching secretary, especially at this time. Because the grade has been finished, the teacher has no right to change it, and it is impossible to know the password of the teaching secretary. Because there are too many things involved, it is also possible that her password is bound to her IP, and others cannot access it if they know it, because this security is very important. There will be many corresponding security measures. All students' information management is managed through the school's Ling Zhan management system. You can only access this system. You can only view some related information through the educational administration information, and you have no right to modify it.
