1. Contact the driving school: First, contact your driving school and ask the relevant person in charge if you have submitted the driving file to the vehicle management office.
2. Internal system inquiry: If the driving school has submitted files to the vehicle management office, you can inquire about your information registration in the internal system of the driving school.
3. Urge the driving school to submit materials as soon as possible: If it is found that the files are not submitted or audited, urge the driving school to submit materials to the vehicle management office as soon as possible to ensure that it can take the subject four exam.
4. Consult the vehicle management office: If the above steps can't solve the problem, directly contact the vehicle management office to consult the relevant policies and regulations of the subject four exam.
