Hey Tushar.

i can assist u in this. If u are having any kind of confusion regarding ur percentile then  use this simp0le formula to find out that.

PERCENTILE P : (N-your rank) * 100 

by using this if u r getting above 965 then u might be able to get a call letter from GIM GOA but that doent seeems so. as the marks u have score will give a percentile between 86 to 89% which is not enough for u get a call letter from GIM. 

But u are having a great choice of different colleges for ur call letter such as 

ABBS BANGALORE

JAIPURIA UNIVERSITY       nay many other. U can also check other option in our site.i am giving u the link.

good Luck

yes there are rare chance of cutoff in goa institute of management is less than 90 percentile.

Last year this cutoff was 225-235 out of 400. Every year the marks and percentile its depond upon the difficulty of exam and number of student scored.

you are closed of cutoff maybe your name is in cutoff list.

You also prepared for CAT exam they also consider this exam.

this is the information from my side i think i will clear your doubts.

Thank You.
