Firstly IBS Hyderabad does not reveal its ISBAT or GD-PI cutoffs. You are not informed about your individual scores let alone your GD-PI scores. The students who get shortlisted are sent an invitation letter for the GD-PI round. Once you have successfully completed the round and have been selected, GD-PI performance along with the college campus allotted to you. However, these marks serve no purpose of cutoffs and therefore should not be considered a general cutoff. Many candidates who got 98 percentile get selected while many with even 78 percentile. Their criteria is unpredictable and therefore no cutoff is fixed.
