Students from other places have to pay a sponsorship fee of 6000 yuan a year, and they have to take exams (because I want to take the exam in No.3 Middle School, although I graduated from No.2 Middle School, I'm not sure if I want it). Generally, you can only pay if you pass the exam.

You can't enter key classes, because key classes have good grades in Grade One, unless you have good grades and know people, or you are the first in all ordinary classes every time, so you can go to poor key classes (though almost, it is definitely better than ordinary classes).
