It is useless to recommend a training class. It depends on the teachers you meet. There is some luck in this exam, and it is also related to the choice of topics you choose. If you want to learn oral English, it is suggested that 1V 1V2 can improve quickly, and 1V2 is ok, but you should find students with the same level. But oral English is very urgent, so we should have basic knowledge as the foundation, such as new concepts and so on. Generally speaking, if you want to take CET-5, you should at least learn the new concept of 1. If you are above CET-6, you must learn BEST 2 well and master enough words before you can pass. I am a teacher myself, but I am not in Dongcheng.
