Tianjin Huajian COSCO is more formal. I participated in the security class training there when I took the first exam. Compared with other institutions, the cost is above average. But the passing rate is really high, because I passed it in one year, and several students I met in the training class passed it almost once, and the worst passed subjects 2-3, mainly because the information class they gave before the exam was really amazing and accurate! (The information class is only for students in the security class, and there is no separate charge. The face-to-face teacher in the early stage is also a front-line teacher. (Unlike some training courses, which teacher may give a good lecture, which one is poor and the quality is uneven. ) guarantee class four 10 class. At that time, a course consultant was in charge of my study, and she would help me solve any problems in time. In short, I am very grateful to Huajian Zhongyuan for helping me pass it smoothly.
