I've got 70% in X & XII and 51% in graduation, what are my chances of getting admission in IIM? What score do I need to get for the same?

Hi, Common Admission Test CAT is national-level management entrance examination conducted by the Indian Institutes of Management (IIM). Apart from 20 Iims, CAT scores are used for admission to various management institutes across the country. https://www.shiksha.com/mba/exams/cat.
