Ministry Of External Affairs (Passport) — class 11 economics paper leaked

I would like to bring to your notice the class 11 economics paper was leaked by some cheats due to which the children studying hard lie same with those who use these foul techniques in order to get marks. I would like to urge to isc that there should be a reteat of examination and this time there should be enough security maintained so that these types of cheats are not performed again at last i would like isc to cancel the leaked paper and conduct a retest as soon as possible
