Hello student

The disability of marks you are facing in your previous marksheet and positive with masses possibly for the cause of improvement examination you have appeared for. This is not a problem for anybody even apply I the respective authority of National Institute of open schooling for matching the mass of your marksheet and certificates. You have to apply it through your respective centres for NIOS of your subdivision or district from which you have appeared for examination of 12 standard and your application will be recommended by the institutional head. Airtel apply with valid documents with the recognition of the head of the institutions.
