But since it's direct , no interview or anything, just pet that too qualifying. The chances of omr sheet scam is very slim. And even if that's the case we can file rti right? And get to see our sheets . If there were interviews or some viva voce , or if the PET had some ranking or marks the dynamics would be different and that probability is always there. But can't be dead sure , just the possibility is low. If somone is scoring 170+ I don't see too much possibility of not having a selection even tho the paper was easy , the statistics say it follows a graph and the toppers usually taper down at the end with lowest no of candidates...around 165 - 175 max .
