The key to learning is to rely on your own learning. It is useless not to work hard. My friend studied in the official career before, and hesitated when choosing. I haven't heard of it before. I thought it was a small institution with insufficient security. Later, we went to the scene and chatted with the teaching assistants who signed up, and it felt good. All of them are full-time teachers, studying for the public examination for about ten years. The teacher is not good and has a good attitude. They had an audition class, and we also took part in it. I suggest that you can listen to their opinions when choosing, according to your own conditions.
