CAT (Common Admission Test) is the most accepted nationwide entrance test for MBA aspirants. Yes, it's accepted by Iims but every top B school has it's own entrance test. XAT (XLRI Jamshedpur), SNAP (Symbiosis), TISSNET TISS MHCET (JBIMS), NMAT (NMIMS) to name a few. Please note that getting through these competitive exams only allows you to appear for the next round in the selection process such as GD/PI and is not the final selection in itself.

The cut-off percentile for CAT (OBC) is 87%. In 2015, it was 90%. It fluctuates depending upon the institute.

You passed 10. So, you are eligible for giving 12th exams also.

You have scored less % in 10th and 12th. You have a good score of CAT. So, you have chances of getting a call for FMS and you are from arts background, you have a chance of getting call from IIM. Also, you have chances of getting a call from new IIMs.

I think that app ko IIM Ahmedabad se MBAkarna chahiye.
