After shortlisting the Candidates, the selected Candidates will have to go through WAT and PI rounds. Selection at this stage will strictly be based on the shortlisting of the candidates done separately for each Category ) on the basis of their Final Composite Score. . The numbers selected in different reservation categories will be in proportions mandated by law.

Personal Interview Multiplication Factor (PIF) = 0.50

AWT Multiplication Factor (AWTF) = 0.10

CAT Score Multiplication Factor for Final Composite Score (CATF_FCS) = 0.25

Application Rating Multiplication Factor for Final Composite Score (ARF_FCS) = 0.15

After the AWT & PI round, admission offers are made by IIMA to successful candidates. The final selection is based on a diverse set of attributes which includes performance in CAT, performance in AWT & PI, academic, co-curricular and extra-curricular achievements, work experience, etc.

Considering all this and the fact that you belong to OBC, you need atleast 85 percentile. The sectional cut offs should be as follows:

VRC: 75

DILR: 75

QA: 75

Overall: 85
