Continue scheduling. Generally, you can schedule the Subject 4 test after passing the Subject 3 test. Here is some additional information: 1. Reasons for unavailability: First, there may be too many people scheduling at the same time, and if your priority is lower than others, you might be bumped off the list. Second, system issues—sometimes the system is under too much pressure, leading to some students being unable to schedule, and you can only wait for the system to be fixed. 2. Subject 4: Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license examination. The Subject 3 test consists of two parts: the road test and an additional safety and civility knowledge test, 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. However, there is no official term "Subject 4" in the regulations.

I was also desperate when I couldn't book the Subject 4 test, but later found a trick: open the 12123 App around 3-4 AM every day to refresh, as the system often quietly releases new slots during this time—don't sleep in and miss it. After failing to book during peak times several times, I chose a less crowded test center nearby and got a slot immediately—the test content is the same anyway. Remember to stay logged into the App to avoid disconnection, check if your personal info is correct, and confirm your Subject 3 results are approved. If all else fails, wait patiently for a week or two; slots will be released gradually—don't stress too much. Many people face this issue with Subject 4 bookings—it's not a big deal, so don't let it affect your driving mood; safety comes first. After about a week, I successfully booked and took the test promptly.

What Causes Car Shaking After Driving Through Deep Water?

The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. There is no specified replacement interval for the throttle body; it only needs replacement when damaged. Below are specific details about the car throttle body: Dirty throttle body causing idle shaking: When the air conditioning is turned on, the compressor also operates. Since the compressor is driven by the engine, its operation increases the engine load, which in turn increases the throttle opening and air intake. If the throttle body is not maintained for a long time, carbon deposits can easily form, obstructing engine air intake. This can result in the engine struggling or barely being able to drive the compressor, leading to idle shaking. Regular cleaning of the throttle body: If driving conditions are harsh, it's best to clean it regularly, recommended every 10,000 kilometers.

Why doesn't the car move when in gear?

Failure to move when in gear is a comprehensive functional fault involving the clutch, transmission, and drive axle. When diagnosing, the first step is to determine the faulty part, starting with checking the condition of both wheels. Here is additional information on the differences between manual and automatic transmissions: Learning period: Manual transmission cars are more complex than automatic ones, resulting in different learning periods. Typically, learning to drive a manual transmission car takes at least one month longer than an automatic. Due to the greater difficulty, the pass rate for the driving test is also lower for manual transmissions. Driving license acquisition: A manual transmission license is classified as C1, while an automatic transmission license is C2. Holders of an automatic transmission license cannot drive manual transmission cars, but manual transmission license holders can drive automatic transmission cars. Cost: Because manual transmission learning is more challenging and has a lower pass rate, its fees are generally cheaper than automatic transmission tuition, which tends to be more expensive.
