Indian Institute of Management, Calcutta has slightly modified it's shortlisting criteria for stage 2 (WAT+PI) of the admission process .

Till last year, IIM C gave :
1) 77% weight to CAT
2) 10% weight to Class X scores
3) 10% weight to Class XII scores
4) 3% weight to female candidates

This year, the changes are:
1) 67% weight to CAT
2) 15% weight to Class X scores
3) 15% weight to Class XII scores
4) 3% weight to female candidates

However, they continue to maintain the same point system for X,XII scores. For example,
a score of greater than equal to 80 fetches the candidate 15/15 in X and XII.
