What are the reasons for being unable to schedule Subject 4 on 12123?

The reasons for being unable to schedule Subject 4 on 12123: 1. Insufficient or invalid study hours. To schedule Subject 4, you must complete 10 study hours, with no more than 4 hours per day. Only after completing the required hours can you schedule the exam. Invalid study hours may occur due to overlapping training sessions, such as studying Subject 1 theory and Subject 4 theory simultaneously, or training for Subject 1 and Subject 2 at the same time. It is recommended not to study different subjects on the same day. Photo discrepancies can also lead to invalid study hours. If the photo taken during training differs significantly from the one submitted during registration due to posture, angle, or makeup, the system may deem it a mismatch. 2. Not meeting the exam cycle. Generally, after passing Subject 3, you must wait for one exam cycle before scheduling Subject 4. The exam cycle varies by region due to differences in administrative efficiency, typically around 10 days. The success of scheduling the exam also depends on local factors such as the number of applicants, exam capacity, and registration ranking. Therefore, there is no exact timeframe for when you can take Subject 4.
As a car enthusiast, I'm quite familiar with the 12123 platform. The main reasons for failing to schedule the subject 4 test lie in system or rule-related issues. For example, routine maintenance or upgrades of the 12123 servers may lead to limited functionality, especially during weekends or peak exam periods with high traffic. Check your phone settings to ensure the app is updated to the latest version, avoiding compatibility issues with outdated versions. Another common problem is unstable network connections—try switching between Wi-Fi and mobile data or restarting your device. If it's a platform-side issue, the authorities will post notifications or updates on social media, so follow the 12123 official account for updates. I've also encountered user input errors, such as incorrect ID numbers or password issues, so double-check your personal information. Preventive measures include avoiding the crowded early morning hours, contacting the customer service hotline to describe the specific issue—they usually respond quickly. Don't worry, it's not a big problem; just handle it patiently.
