1. Contact relevant departments: contact the admissions office or education examination institution related to the academic examination in time, explain the situation to them and ask if they can correct their mistakes. They may provide specific operating instructions or require relevant certification materials.
2. Modify the registration information: If the registration period is still in progress, some examination institutions may allow you to modify the registration information. Log in to the registration system, find the option to modify the registration information, and make modifications according to the system instructions. If the system does not provide modification options, you can try to contact relevant departments for consultation.
3. Remedial measures: If the registration information cannot be modified, you can explain the situation to the relevant departments and ask if there are other remedial measures. They may need relevant supporting materials or special audit procedures.
