Subject 2 and Subject 3 have a total of 24 hours. If the students need to pay for the extra hours, it is recommended to find a driving school where they can practice driving without any hours, in case they need to pay extra driving fees if they exceed 24 hours. Furthermore, let&;s talk about whether 24 hours is enough, a total of 24 hours, if it takes 12 hours for subject 2 and 12 hours for subject 3. If the coach is teaching one-on-one, you have a strong learning ability, and 12 hours is just right. But in case you fail the exam, you need to practice driving again before the next exam, and it will take another two hours, so there is not much time left for the third exam. For students with slightly poor learning ability, 24 hours is still slightly insufficient. Most driving schools, including our driving school, are not limited to class hours, and students practice until the meeting before taking the exam. This will help students to be more familiar with the points, practice driving skills and pass the exam more easily. I hope I can help you, and I wish you get your certificate early!
