I am assuming you are from general category. Based on your overall academic profile, you will need to score atleast 98.5 percentile in CAT to get a call for the next round.

All the best!

Hi. The cutoff for IIM Lucknow is at least 50% in +2 and a high percentile in CAT. All the IIMs consider CAT score for the admission. Getting a high percentile in CAT will land you in your goal.

Good Luck!
