I will say exams might be one of a thing they do. How many people will really go for taking an exam in life? Your life is made of the exam? You heard those philosophy in the world religion they say?

But it has become one of those very elaborate process. I have seen.

Unless its human nature they believe in exam, probably just one side of population they go for that, and become part of that Unit, or something by the Upper Military Commander. That is one nature of life. I cannot tell you the rest of the other lifes without the exam. 

Some does an exam for living...?!
