When exam paper leaked is it better to conduct the whole examination again or only leaked subject?
As there is a question paper leakage in CBSE examination paper of 10th class mathematics subject and students and parents were come on roads and agitating.As when I was studying 10+2 for the 1st year mathematics question paper was leaked so the whole examinations were scrapped and scheduled a new examination for all subjects.1)What do you think is it appropriate to conduct a new schedule of examination or only for a leaked question paper of a particular subject?
2) Do you think the question paper which is leaked to a particular area or region the examination should be freshly conducted or it doesn't matter a fresh examination should be conducted in all places?
