Hello Himel, Greetings!

CAT cutoffs for any individual IIM is not a single number and they vary highly depending on your profile.

IIM-A insists much on diversity so cutoff %ile depends on other people's marks of the same field. Academic scores(10th, 12th and Graduation) above 80–85% is kind of must. In CAT, Mostly for engineers it is above 99 %ile and for fresher boys it is even higher. Non engineer girls with a good profile can expect a call at 96–97%ile also.

IIM-B puts a lot of emphasis on work experience so for freshers it is way too tough. Equal emphasis on Academics like Ahmedabad.

IIM-C is most flexible with work ex and acads compared to A and B. CAT is usually above 99 %ile.

IIM Indore’s call is most specifically dependent on your 10th and 12th marks and those having a low score in it ( below 87–88) should not expect a call at any CAT %ile.

For new IIMs, there is a common interview which you have to appear if you have no call from old IIMs. They usually have a cutoff around 96%ile.

Thank you, hope this helps.
