At that time, when I applied for the exam, both Zhong Gong and Tu Hua had contacted individuals. I feel that the strength of these two schools in remedial classes is similar, because most of the good teachers are concentrated in first-tier cities or provincial capitals, and the lowest-level municipal demand classes are often ordinary teachers with young age and short qualifications. What I can give you is actually the learning atmosphere. Of course, you let people with a particularly poor foundation go. No matter what teachers they listen to, they feel very good. After all, they don't know anything. Everything sounds new.

Whether to apply for a written test depends on your personal foundation, but it is not necessary to apply for an interview. As for the agreed class pass rate you mentioned, it is always not high. Otherwise, everyone signed up for the agreed class. I suggest you proceed from your own situation. If you want to enroll in the written test remedial class, you can choose a shorter course, and then you can choose a module to listen to. If it is not suitable, there is still room for choice.
