can I get entry in IIM with 94.2 percentile

You have a pretty good CAT score and you may get a call a call from the newer IIMs but that also depends on your past academic records . For example if you have scored above 80 percent in 10th and 12th and more than 75 in graduation or if you have a work experience for atleast 2 years or have got any achievements. IIMs do consider all these factors and the ratio between number of students called to the total number of seats.  But if you get a call just perform your 100 percent and you'll be good to go.

Good luck
