Dear Aspirant, if your graduation percentage is more than 50% then you are eligible for CAT exam. But in order to get good MBA College through CAT you need to make your preparation at the top level and you need to get 96+ percentile to get IIM and another thing is if you have some work experience then it would really help you in your placement as experience really matters in MBA placement. I hope you are clear now. If you have any other doubts feel free to ask. All The Best!!!
