Many candidates responded and used their coaches. They did not adapt to the opening of the test car. What is the difference between coaches and test cars? 1. The court test car is burning gasoline, strong power, training car is the majority of modified steam burning, so the students loose clutch on the jitter is not so obvious, it is recommended that the coach train oil on the start uphill training. 2. The free travel of each car clutch is not the same. It is recommended to loosen the semi-linkage before releasing the handbrake. 3. The examination gear of the examination car is used frequently due to its high frequency of use, so the gap is relatively large. The training car is basically a one or two year car gap is relatively small, it is recommended that the coach informs the trainee that the file should be light when the file is stopped. Hang a file into reverse gear. 4 The examination seat has a high frequency of use and the seat is lower. It is recommended that the seat cushion be unclear. 5. The coaches are equipped with small reflectors to facilitate the coaches to observe the traffic conditions while the coaches have no small reflectors. It is recommended that the coaches tell the trainees to watch the mirrors of the original car. This difference requires the coaches to explain the students in the teaching process and how to adjust them in this situation. 6. When the trainer train was in training, some wiper blades were replaced with boneless ones, and the examination vehicles were all boned wiper blades. Therefore, when the wiper rivets were viewed, they were different. 7. Ask the coach to inform the trainee that the handbrake should not be pulled too tightly during the examination so as not to affect the examination. These are test-taking techniques. Candidates can make appropriate adjustments based on the difference between coaches and test cars.
