Fear works wonders if controlled within and overcome. Fear makes self as self in other for want of human dignity,pleasure-seeking and self-seeking-knowledge. Without fear,one can never achieve anything in world. Fear of exam must be overcome by passive-mindset about success(which is between 35% and 66%) in subject. Subject has to be subject in its self.Or otherwise subject will be made to be subject in self by other/s at next.

Fear is complex thing which must be had among humans in society at first and overcome by knowledge(subjective-mind) at next.
