Hello, 

  All the reputed  Institutes in India has eligibility criteria for MBA, students have to meet it before admission. General eligibility is that 50%(45% in the case of reserved category) marks in graduation from a recognized university and need to secure good percentile in national level entrance tests(CAT, MAT and CMAT, etc...) or admission seeking institutes entrance tests like LPUNEST, DSAT, XAT, and SNAP. My advice to you would be that try to improve the marks and then apply for an MBA. 

Hope this information will help you.

Good Luck!
