During the examination, the invigilator is responsible for recording and managing the examination process. If you forget to sign, you can contact the invigilator to make it up. Check whether there is the contact information of the invigilator on the checklist, or consult the relevant invigilator.

When dealing with the unsigned problem of subject 3 exam, you should contact the invigilator or driving school as soon as possible to deal with it and provide relevant certification materials. At the same time, try to avoid delaying time, so as not to affect the subsequent inspection or treatment.
