I signed up at Chengdu Wu 'an Driving School and took the first course, but found that the coach's teeth were too long, so I had to eat, drink and smoke. It is said that you can take the exam yourself now. I also took the Wu 'an exam in Chengdu, but my master doesn't smoke or drink. At that time, he helped us brush the school time. According to the master, the tuition fee can't be refunded after the exam. I just heard about it, but I think the second and third subjects will often contact the master, such as practicing car, road, long-distance running and making an appointment for the exam. Look at you like that, spend more money in the future. You can ask the school if you can change to a master's degree. It's best not to ask your master first. You can ask the school quietly before making plans!
