No system is without loopholes, besides i argue that in cases where you have objections, note and check their results before getting pessimistic. NTS has its own demerits.
You think someone can do the justice with questions after wasting time in cheating, YOU SERIOUS? :o In CE papers? and that too with contemporary trends??? and its also assumed that the checkers, having enormous experience can not filter it out? i hope you are kidding..(Objective part alone can't make the difference)
I don't think there is any point of checking the IDs of guys, you remember after first two/three days of checking. face recognition???? Chill out people, except minor/segregated cases, don't raise question on the whole exercise.
I don't think we are expecting biometric system for 25000 thousand candidates every year, or CSC monitoring for the whole web of centers. are we????
