A friend's child will go to primary school in Xuyi in the second half of the year. Will they go to primary school or affiliated primary school?

I heard that a small number of students study well. The child of one of my classmates is in the sixth grade this year. The test scores are all around 1 18, and the children are ok. Then another classmate of mine asked her, your child must be in the first three buildings. As a result, my first classmate replied that they were not in the top ten, and all the children in the class did well in the exam. By the way, many quizzes are generally full marks. I am so depressed. My child has been promoted to the fifth and sixth grade of primary school and has never got full marks.
