Sir i want to do MBA in JNU, it accepts CAT score from this year  but application date is compleded. What i have to do..?

Ask this As a question if Someone knows he will answer

If application date has passed then u should go to the institution and have a face to face talk about your problems with the concerned authorities but if you are not in the same city or state a brief discussion through a phone call I would suggest though the former solution would be more affective.
Hope that helps
