Technically there will b asians who are bad at math right?

I live in asia, in my school there are 7 classes for each form/grade....

The top classes are preety good at math, then there are the bottom classes..

Let say the bottom three classes are bad at their studies...

So one class has about 40 students, three classes would have 120 students...

So there would be 120 students who are bad at math for each form in almost every school!

But i am not one of them! And i represnt my school for track events...
