Hello Aspirant,

Each Institute including IIM prepares a merit list to call students for next round of interview and WSAT which is based on your aggregate score which comprises of many factors such as CAT marks, 10th 12th and graduation percentage, work experience etc. with different weightages for different IIMs.

If you are targeting to get top IIMs like IIM A, B, C then try to score more than 99 percentile and for new IIMs try to score 95 percentile in CAT Entrance Exam. Other than IIMs, To get into  top private colleges like FMS, JBIMS Mumbai etc. You should have more than 98-99 percentile.
