The feeling is average, but the teacher's personal experience is quite rich, so a class is basically listening to the teacher tell their stories. ...

In fact, Band 4 has to be reformed recently. I don't know if New Oriental has followed the reform. I suggest you ask them about the reform first.

Tell the truth, you can pass the college entrance examination level 3 and a half. Basically, you can recite words, do real questions and listen to listening comprehension.

If you must go, New Oriental is the first choice!
