It's polite to call the school admissions office and ask what to say.

Hello, if you need to consult the school admissions office, you can call directly. After the call is connected, you can say: hello, is this the admissions office of a school? I want to ask some questions about the enrollment work in your school, mainly because I don't know the specific enrollment policy. My child is going to apply to our school today, and I also want to know some specific matters of the school, such as specialty setting and graduation distribution. Just ask them what you need to know. Try to respect each other in your tone. After all, they have been answering similar calls and may be a little impatient, so be gentle and polite.
