Reforms of education

A little bit about reforms
What I want to change
1)system about teachers
2)quantity of forms
3)Exams

Teachers
It is difficult to say but in our modern world there is this problem. Some of teachers are really bad. They can't even build their sentences. This applies to young the teachers. Furthemore,some of teachers too angry, they don’t have enough patience. And finally, some of the teachers, I cant even сharacterize this type. They come into lessons and just sit at their mobile phone and do nothing. I am suggesting to select teachers more carefully.

Classes
Quantity of classes
There is not much to say. I am suggesting 12th classes,because there are a lot of tems which we have just *run*.
