Keep it genuine. This exam is not that easy, instead very peculiar to other exams. The awareness and consequences are known to many now. People have been acquainted of the requirement of this exam and competition is increasing every year. For me, 2015 was my first experience, and many of my perceptions have been rectified after taking papers. Keeping in view the scant ratio of pass percentage, one needs to be very creative, smart, assiduous and different from others.
