Hello Pooja,

Your academic career seems very good.  You have done good in CAT. 80 - 83 Percentile range shows that you can definitely expect IIM.

Talking about IIMs, as you might have researched about the last few years' cutoff, the cutoff for OBC of all IIMs range from 80 Percentile and above.

As per the rankings of IIMs, the top five IIMs are-

1. IIM Bangalore

2. IIM Ahmedabad

3. IIM Lucknow

4. IIM Calcutta

5. IIM Tiruchirappalli

You should definitely give priority for the above five IIMs and try to get admission there. Considering last few years' cutoff, you should definitely get admission in any of the IIMs.

Best wishes.
