IIM Ranchi offers an IPM Program based on SAT / IPMAT Scores. The Expected Cutoff for IPM via SAT is 930.
Apart from this, we don’t have many criteria to base this admission on. So the benefit of the doubt goes to applicants having SAT scores soaring at about 1100–1600. The admission criteria for other programs are more flexible as it is based on parameters such as 10,12, UG scorecards. So it’s highly unlikely that even high marks will get you into IIM Ranchi.
