If you fail the Subject 4 test, you must wait ten days before you can schedule a second attempt. The Subject 4 exam question bank mainly consists of the following: 1. Starting from January 1, 2013, the Ministry of Public Security released the first version of the Subject 4 question bank, which included 700 questions for small vehicle licenses (C1, C2, etc.) and 1023 questions for large vehicle licenses (B2, A2, etc.). 2. From May 1, 2013, the Ministry of Public Security updated the second version of the Subject 4 question bank, adding 100 questions for small vehicles, bringing the total to 800 questions, while the large vehicle question bank remained unchanged. 3. The Ministry of Public Security Order No. 139 of the People's Republic of China updated the new version of the Subject 4 question bank. According to the Driving Test Guide, there are now 1240 questions for small vehicles and 1715 questions for large vehicles, including the latest local questions.
