Why is Subject 4 not showing up for appointment?

[NoraDella]

This situation occurs because the system defaults to scheduling Subject 4 on the same day after passing Subject 3, and it has already been automatically booked for that day. Therefore, attempting to apply again will result in a duplicate appointment notification and it won't be displayed. Relevant information is as follows: 1. Subject 4: Subject 4, also known as the Subject 4 theoretical test or driver's theory test, is part of the motor vehicle driver's license assessment. 2. Assessing Driving Ethics: After the implementation of the "Ministry of Public Security Order No. 139 of the People's Republic of China", Subject 3 test was divided into two parts. In addition to the road test, a safety and civilization knowledge test was added, commonly referred to as "Subject 4", which assesses "driving ethics". Since this test is conducted after Subject 3, it is commonly called the Subject 4 test. Officially, there is no such term as Subject 4.
