It's like it is a standard. 30 is ok
but OH my word if it is 33.
boastful mother " My Anna is in a class of 27, i was so relived"
I ask in relation to a market forces question Xenia asked. Teachers are relatively low paid she says becuase it is easy to become one.
So i wondered why they arn't paid more and we dont have two teachers per class, or why the standard isn't 15 per class.
Why that number? why 30?
