The Naga Students Union, Chandel district, and Kuki Students' organisation said in a joint statement that more than 7,000 students had not been allowed to write the examination conducted by the Board of Secondary Education Manipur in the past two years or so.
They alleged that the BSEM had collected enrolement fees, but failed to issue admit cards on earlier occasions.
Sources in the secondary board revealed that cases were reported that candidates, particularly from interior hill districts, who had studied at various educational institutions in valley districts wanted to write their examinations at the hill districts, but this went against the rules.
