This seems to be similar in the whole country, and the education prices in the United States and Lebanon are not bad. And I heard that they have free audition courses, and other institutions charge for audition. After all, you have to learn all English textbooks, mainly because the teacher's class fees are very expensive and scarce in China, otherwise the price will definitely be similar to that of ordinary IELTS TOEFL. For example, education in the United States and Lebanon is considered as secondary. The key is to be satisfied, to really improve your grades and learn something.
