Hello Aspirant.

Hope you are doing well.

Really sorry but it is not quite predictable because it actually depends not only on your Cat percentile but also on your over all profile. Sometimes IITs don't call candidates even if they score really high in Cat. And sometimes even the best Candidates don't go through. But since your query is specific to getting calls, go through this link to get college wise call cutoffs for IITs.

GOOD LUCK, STAY MOTIVATED AND HOPE THIS HELPS.

Thankyou.
