Is there a reliable IELTS training institution in Beijing? I consulted several institutions, and it was very confusing.

Let's establish an IELTS study partner. My classmate recommended one to me. Beijing International Trade Center called it my favorite institution. I just finished my audition. I feel that the teacher is not bad, much better than a large organization, and the main price is quite suitable. I'm just saying how cheap your price is They said that they don't advertise like other institutions, but rely on word of mouth to recruit students.
