It must be true and false, and you need to distinguish it carefully by yourself. However, generally speaking, when we choose an institution, we can refer to the following conditions:

First: teaching content, first of all, we should know whether his teaching content is comprehensive and systematic enough, and it is best to keep pace with the times and have his own method content in it, instead of following the book.

Second: teachers, preferably teachers with official authority certification, the learning efficiency of good teachers is still very different.

Third: learning efficiency, what the teacher says and your own absorption ability. Of course, this piece should consider not only the basic skills of the teacher, but also your own ability and cooperation with the teacher.

Generally speaking, if you meet the above three conditions, it is a good practical training. If you are satisfied, please accept my answer. Thank you!
