hey,

there is no pass marks mention to crack cat exam. however there is institution wise cut off to get shortlist for further round held in particular institute.

like get calls from  iims  above 95 percentile in cat is required. some more top institute like PUMBA, sp jain, symbiosis  has their own cutoff for cat rank holders.

to get admission in top institute try to score above 90 percentile in CAT.

hope you may understand.
