You can go to e-say to have a look ~ I reported to work there, and the teacher is very responsible and the level is good. Throughout the class, I teach oral English one-on-one, and I will record it all the time. After class, I can easily find my own shortcomings from the recording, and after class, the church pays close attention to your learning dynamics and comments every day, so that you can clearly know where you have made progress and where you have failed, and then improve.
