Thanks for your query. Which entrance exam do you want to opt for? It seems you have questions for all the entrance exams including NMAT, CMAT and KMAT! All exams have their individual weightage and credibility.
Now, to talk about the colleges accepting KMAT scores. Several private colleges accept KMAT scores; however, the number of government institutes are less.
