I don't think it's necessary to list this thing. In fact, every school is not on a starting line. If the enrolled students have a good foundation, they will naturally do well in the exam.
I think it is not wrong to choose from the following aspects.
The first is the faculty. Huihong's teachers are basically from Yali and Changjun, and the principal is also a master and doctor of St. Thomas University. He is also the best lecturer in New Oriental and once taught in Changjun. Personally, I think this piece is no worse than other schools.
Then it may be teaching management. Basically, repeat schools are all about militarized management, and the details here are better. For example, the mobile phone signal shielding device will be turned on regularly, and professional equipment will be used to detect whether electronic equipment is brought into the campus. What's more, it is a small class system, and each class has a full-time teacher. I think this piece of music is very good.
Finally, some people may take a fancy to the campus environment. In fact, I think most people choose to repeat for their grades, so I don't care much about this one.
