Hi Nitesh! You are right. MBA can be done after the completion of your graduation as it is a post graduate program. As per the eligibility criteria of CAT and other top MBA entrance exams, you need to be a graduate with minimum 50% marks in aggregate for general category candidates and 45% for reserved category candidates. For various other exams like XAT, IIFT and others, there is no cut-off percentage for graduation. Final year bachelor's degree students can also apply.

As you are in first year, focus on your college studies now. You may start thinking about preparation from second year onwards.
