IIM

Any graduate from a recognised university is eligible to appear for CAT exam to seek admission in IIM. You are eligible to appear for CAT with B.Sc degree if you more 50% marks in your degree course.

Hello Anup,
Any Bachelor's degree will do in order to pursue your MBA from an IIM. However, ensure that the degree (B.Sc, BMS, B.Com, etc.) is given from a reputed and/or Govt. approved University.

To get admission in IIMs, you need to clear CAT. You need to score at least 97 percentile in CAT to get a call from IIMs. A good academic/work profile will definitely get you in IIMs.

For ranking you need to check Times of India Education as it would provide you the idea for top B-schools.

As a general candidate 90 percentile with similar marks in all sections to meet sectional cut off criteria can get you a call for interview in IIM-Ahmedabad. Higher percentile will be better.
