It feels good to repeat my studies in Zhengzhou New Century School this year. I suggest you go. However, you must enter the class of Tsinghua Peking University. In that case, teachers' equipment will be better, and students' level will be higher and more competitive. However, because it is a school in Zhengzhou, the management is relatively loose, not high-pressure review, but more emphasis on methods. Guohua suggests that you don't go. I am in the same campus as the technical secondary school, which is a bit confusing. If you are a science student, you can go to Zhengzhou No.1 Middle School. They have special science repeat classes with a relatively high level (the cost is also relatively high, like 10 thousand a year); But if it is a liberal arts, I don't recommend it, because there is no special repetition class, so I have to insert a new class when I go.
From other cities, I heard from my classmates that Luoyang No.1 Middle School is better and stronger, but it is estimated that it is more difficult to enter. And such a school must be stressful.
Still have to decide according to your own situation and see your own choice. Good luck!
