CAT Scores

If you can secure 50% in CAT and 70% in MAT you are eligible to apply. Since IILM Admission team look into the overall profile of the candidate, entrance exam score is just one of the other parameters.

I would suggest you to opt for a career aptitude test. This will help you to gain an insight about your personality. You will be able to figure out the careers, which you may opt suitable to your personality.
These tests are not always accurate but they definitely provide you with some sort of guidance, which is helpful on deciding your career path. And a word of advice, don't worry and stay relaxed. Everything will be fine. Just give some time to yourself.

IIMs have a hard cutoff of 50 percentile and no matter how much you score in CAT, you will not receive a call for IIM if your graduation percentage is less than 50. However if you are above 50 percentage, then to get into IIMs you will need to score really well. I would approximate it to be close to 99.75 percentile.

Good CAT or MAT score will help you to get admission in a prestigious B-school. Campus placement is totally dependent on your performance in MBA and selection process.

Yes, you can get admission in top b-schools, if you score above 90 percentile and should have graduation degree with minimum 50%.

Hi Siddharth,
Last years cut-off for FMS was 98.6. It is safe to assume that the minimum required percentile is usually close to this.
