Hehe, I stayed in our high school when I was a sophomore. I suggest you ask the school if you can go directly to the experimental class if you register. If possible, the cost performance is higher. If not, you should tell the school to think about it first. If you refuse directly, the teachers will not pay too much attention to you in the final review process, which will have a bad influence on your academic performance. If your school is ok, it's safer to sign a contract, and you don't have to bear the pressure of the senior high school entrance examination. If the school is not good and you think you can get in, then don't sign it. Once a contract is signed, you can't break it. Unless you go abroad. Someone in our class signed a contract and went abroad, and there was nothing the school could do.
