Hey,
There are 20 IIMs(Indian Institute of Management) in India and each has different set of eligibility criteria. IIMs offer admission based on your CAT scote.
In addition to this,the past academic performance, relevant work experience, writing ability and personal interview also plays important role for your selection.
The basic eligibility criteria for CAT is that you must have completed your graduation from a recognized University. And if your diploma is equivalent to high school exam then you are eligible.
Hope this helps.
Good luck.
