No purpose. Mainly English is divided into AB classes. Actually, class B doesn't matter. If the school is good in the future, you can transfer to Class A. The teaching content of Class AB is exactly the same, and there is no difference between good and bad.

The placement test tests Chinese, mathematics and foreign languages.

In fact, the placement test is mainly in English, and the problem of placement in AB class will be considered.

But there is no distinction between good and bad classes, and every class is the same.

There is no key class,

Just brush up on your English,

Not particularly difficult,

That's how I got here.
