First, the reason why I didn't choose the above training courses is that there are many training courses called Guang Bei and Zhongchuan. I specially called us to ask, and the school replied that these training courses had nothing to do with the school, but were all for the convenience of enrolling students with such similar names. The state does not allow universities to offer pre-test training courses. Personally, I feel that this name is quite fake, so I didn't choose this class with a university.
Second, it depends on the teacher. You don't need to read the resume of the training teacher. Just manage the schedule directly, depending on how the schedule is arranged. When is the teacher's class? Generally speaking, the examiner and professor from Nakagawa come to teach. Then ask clearly, if you are a few days a week, are you sure that this is arranged by the teacher from beginning to end? Is there a promise not to change teachers?
If you ask the above questions clearly, you will definitely not be cheated. I hope I can help you.
