The certificate is usually when you get the admission ticket. Junior high school will give you a portfolio, and you need a copy of what awards you have won, as well as various certificates (such as the certificates of students who are indicators or directly affiliated students). The class teacher will specifically mention it.
There is no senior high school entrance examination in No.2 Middle School, and the distribution method is S-shaped from the first to the last according to the students' grades (naked marks, excluding any extra points). Finally, the teacher draws lots to decide the foreman, and the direct students are evenly distributed to each class. So you don't have to worry about good classes and bad classes. Everyone is the same.
If you become a direct student, the school will ask you to start school early. The specific school will inform.
What you need for the exam, you will know when you get the admission ticket. ~~
