First of all, the teaching level, what kind of teachers teach what kind of students, here I am talking about full-time teachers, professors who quit after one or two classes, except all well-known TV workers. The second is whether your relationship with the local high school is hard enough. To put it bluntly, it is whether money and relationships can be in place. If the above two points can be achieved, the normal operation of the training course should be no problem.
