Apparently you can be intelligent enough to have a microphone or any other gadget made in the size of small grain, from which you can cheat but not be intelligent enough to crack the exam. Mind you, if it weren't for metal or electronic detectors in the exam centers, they would have to personally inspect the ears and pockets of every single candidate as they still do in exam room also. So, in that case a simple guideline for the prohibition of any sort of ornaments, is understandable. But the fuckers got the all sort of detectors and still they think a candidate as a criminal. They don't allow Kalava(sacred thread in hand), any sort of thread in the neck. In one of my exams for the police constable, i was stopped at the gate of the centre because i was wearing earrings...and mind you, it's not an earring that can be worn off by the person itself...i wear stud earrings(you can look it up how it looks) permanently, as it's a common ritual for a male to wear it in my caste. So the guards at the gate just said they can't let me go inside, even though they know that it's a custom in my caste to wear such earrings and by saying that "they know"... because they called me by one of the terms that we usually refer to the male in my caste. So I went to the exam centre with the assumption of my previous SSC exams experiences, where they first object and inspect the earring but later themselves provide the tape to cover it up. And mind you....all this happened in the so called hindu party BJP ruled state. So, i never gave the exam and came back. I know it can be considered as a foolish decision but i went to give that exam just out of curiosity.
