NTS takes the tests and displays the marks but don't show the paper of topper. Lets suppose a person give 60 correct answers and his marks are also 60 then he can say the system as transparent but only to the extent of his own test. Another person giving 20 correct answers secure 80 marks so how can we know that there is honesty because we don't know about the paper of the second person nor he accepts that he was having a poor paper.
