You seem to have missed out the name of the institution regarding which you're seeking information for its admission process. You can write it down in the comment box below this.
Anyway, as per the eligibility criteria for CMAT candidates needs to be a graduate in any discipline with a minimum of 50% marks for general and OBC categories while SC and ST need a minimum of 45% marks.
