Mehta: it is in packed in an iron box with a lock which is not an openable lock. Once it is locked it has to be broken. it is one time use. Two trunks of question papers go in a sealed metal box. The vehicle with carries the strong has GPS and it is cracked in the head office of NTA. Even a small movement is recorded. if he holds it would be recorded. The vehicle contains two sets having different questions. They are put into two separate Banks in strong rooms.

Mehta: 24 packets will be filled with completely differently jumbled papers. This packet of 24 is put in a cardboard which has a watermark number which cannot be duplicate easily and city code then Centre code and the packet number.

Mehta: these papers are placed in a box which has the seal which cannot be duplicated. The questions are jumbled up.

J Narasimha: all this was the subject matter of the Radhakrishnan committee.

Mehta: let me complete for my satisfaction.

Mehta: one cities open nobody outside there is permitted to enter the printing press. Everything continues to be video recorded. For each classroom there have to be 24 students. The question paper along with the OMR sheet is placed in a sealed envelope. Nobody can change this. And there are four types of question papers which are coming to you. The printer does not know that for which exam is printing the paper.

Mehta: this goes in a sealed cover to two separate printers. They are identified printers with CCTV cameras and surveillance of CISF. The person goes with the box with some digital key. The person does not know the answer of the key and how to open the box. When he reaches the printer would personally call the Director General that your man has reached and the Director General would talk to the person. Then the Director General would give the code to open it.

Mehta: after that another set of moderators select 100 each and prepare four question papers. So they are also not aware which question paper will ultimately go and become the question paper for the students. Out of the four question papers the Director General NTA selectd two question papers for the same exam. So till then nobody knows which question paper will ultimately be the question paper.

Matter taken up.

Solicitor General Tushar Mehta: the system according to me is foolproof. At some stage there is a human error and human intervention that would depend upon the person. Generally this system is difficult to breach. Several moderators are asked to prepare a question bank of say, 500 questions for a subject so that one person is not deciding which 100 questions come in the question paper.
