3)But after Completing the CAT course and all the tests,in which collage i get the admission.such as government or private or it depends on how many marks i have got in examination.

Any student with a minimum aggregate score of 50% (general category) and 45% (reserved category) in his/her graduation or degree exam from a recognised university is eligible for an MBA degree. Final year students are also eligible for applying in the entrance exams for MBA.
