Hi Sakshi, Yes you eligible to apply for all MBA colleges irrespective of whether your undergraduate degree is correspondence or regular . You don't need to convert your distance learning to internal since it is not a necessity. You can take admission directly in good MBA colleges or you can sit for entrance exams for getting into reputed Colleges like IIMs and others. As long as you score exceptionally good score in entrance exams and crack the interviews( where you might have to give a valid reason for distance learning course) , the fact that you did your undergrad through distance learning doesn't matter much.
