My friend got a total score of 7 in IELTS and has gone out now. She studied for some time before, as if she had studied at Langer. She told me that the teacher behaved well in class and was very serious and responsible. At that time, my friend went to Nanning to take the IELTS test. She said that only Nanning in Guangxi can take IELTS, so you can learn more about it. Good luck!
