According to the regulations, each subject has two exam opportunities for each appointment, but it can be retaken once at a time. If you fail in subject 2 again, you need to make an appointment again after 10, which is equivalent to the exam opportunity of subject 2 and subject 3 10, and the number of appointments is limited.
According to the "Regulations on the Application and Use of Motor Vehicle Driving License" issued by the Ministry of Public Security, during the validity period of the driving test, each student will have five opportunities to take the subject 2 and subject 3 exams respectively.
According to the "Regulations on the Application and Use of Motor Vehicle Driving License" issued by the Ministry of Public Security, if you retake subject 2 or subject 3 or 5 times or more within the validity period of the driving skill certificate, all the previous exams will be invalid, so you have to pay more to retake. Subjects 1 and 4 are theoretical, and there is no limit to the number of exams, so the probability of passing is greater.
