XAT

Likesh, there are different ways of admission in MBA. Some institutes prefer CAT/XAT/ MAT scores only for admission to MBA course. And to appear for CAT/XAT/MAT etc student needs to have 50% in graduation. But eligibility criteria varies for various Management Institutes or Universities, they can take different %age in graduation along with CAT/ MAT/ XAT scores.
Another way of admission is internal tests or admission criteria of individual Management Institutes or Universities.
Yet another way is of management quota seats.
If you appeared for any of the tests go for admission using that otherwise use your graduation scores for admission in some good private university. Avoid going for management quota seats as they generally are expensive.
In fact there are some universities that also offer scholarships to meritorious students thus making quality education affordable to all.
You can check the websites of some universities for more details.
Good luck.
