Hi dear,

OPENMAT is a national level entrance exam conducted by National Testing Agency for admissions to MBA/PGDM courses offered by  Indira Gandhi National Open University (IGNOU).The last date for ignou open mat registration is June 30th. Also the change of regional center can be done easily by giving an application in the last RC. However, sometime the whole process may take a time of 1 month or more. But you can easily give exam from anywhere in India without change in RC.

Hope this helps.. Good Luck
