To be honest, anything less than 95 percentile in CAT is going to be less for being shortlisted for FMS irrespective of the Academic profile that you have built up.  A Candidate with at least 97 sectional weightage will be shortlisted at FMS. So it is important to focus more on VARC section while not leaving other sections. Higher cut offs are due to the intensity of the competition at FMS, Delhi. Previously FMS used to consider overall CAT score for shortlisting. However since the past 2 years, FMS has been giving sectional preference and weightage. VARC occupies the top position with 40% weightage. FMS Delhi usually has the highest cut offs for its 285 seat intake. FMS is one of the premiere Institutions and hence the admission process is never easy. The selection process includes 3 stage method. They are:
