I don't know much about No.4 Middle School ... but I think it seems quite general.
No.12 Middle School seems to be a school with serious polarization. Students who study well study well, and students who study poorly have poor grades. ...
Why not go to No.8 Middle School ... In fact, No.8 Middle School is the best ... It costs money, so why not find a good school? ...
For reference only, I hope I can give my aunt some help O(∩_∩)O~
