The subject 3 test is an important checkpoint on the road to obtaining a motor vehicle driver's license. It consists of two major parts: the actual road driving test and the safety and civilized driving knowledge test, which supports the entire test system like two wings. The actual road test, as the name suggests, is to test the driver's driving skills and safety awareness in a real road environment, just like a practical drill to test the driver's real level. The safe and civilized driving knowledge test is more like a theoretical test, which examines the driver's understanding and mastery of traffic laws and safety knowledge. 
Don't panic when you think you've passed the actual road test for subject 3, but you are still prompted that you need to take subject 3. This may be due to the system not being updated in a timely manner and the status of your exam has not been accurately reflected. It could also be that your test results were not entered into the system correctly, so the system is unable to update your test status. At this point, you need to get in touch with your local driving school or test center in time to check if your test status has been updated. If you find that your status is not updated, you should ask them to update as soon as possible so that you can move on to the next stage of the exam. 
There are a few things to keep in mind as you prepare for the Subject 3 exam. First of all, it is important to arrive at the test venue early and familiarize yourself with the test room environment, which is as familiar as a soldier is to the battlefield. Secondly, it is necessary to strictly follow the instructions of the examiner, which is the key to a safe journey, just like a navigator following the guidance of a compass. Finally, keep a good attitude, not nervous, not anxious, and firmly believe that you can pass the exam. If you encounter any problems during the test, you should respond calmly and ask the examiner or apply for a new test.
