Hello aspirant,

Although the going may be difficult given your low graduation marks, you must score more than 96 percentile to be called from IIM-A/B/C/D for the general category. If you perform better than the 75th percentile for the reserved category, you put a lot of effort into it.

So as you are an OBC category student I suggest you to try to score above 85 percentile.

Thank you

Hope this information helps you
