Education officials say they are committed to holding free, fair and peaceful examinations, and that examination centres are being filmed and special "flying squads" of officials are making surprise visits to the centres.
They say at least 400 students who have been caught cheating have been expelled.
But they say the government alone cannot stop cheating without help from students and parents.
"What can the government do to stop cheating if parents and relatives are not ready to cooperate? Should the government give orders to shoot them?" the Times of India quoted Bihar Education Minister PK Shahi as saying.
