Hey Aspirant!

Your score is not up to the mark, to be very honest. Because your score in 10th, 12th and in graduation matters a lot to get shortlisted in the IIM. But you may apply for CAT af course but to get shortlisted you must have to score above 99.5 percentile or may be 99.8 to get the chances of getting calls. Because there are lots of students who apply for CAT at the same timw you do. 

So there will be hard competition with these marks you have scored. Please don't get offended. Try hard, practice a lot to get to the 100 percentile, not any college will regret calling you.

Thank you.
