Hii aspirant,Coming to your question I would like to tell you that the IIM criteria for admission in the top management institute at present there are 20 ions in the country , so you must fullfill the eligibility criteria to write the exam and hope for the best the basic elligibility criteria for the cat exam is -

• He must have a bachelor degree with atlest 50%marks 
• The final year students can also apply.

It is important to note that different IIMS give the different weightage  to the cat score , academic cutoff, work experience etc.

So just give your best in the cat exam , just focus to score a good percentile.

Hope this helps you , feel free to ask if you still had a Doubt.

Good luck.
