Dear aspirant,

According to your question and your percentile in cat there are no chances that you would be called by the top IIMS because the cut offs are higher than 50 percentile.

Generally top IIMS keep their minimum criteria of 60 percentile. Maybe you can get some new iims like ranchi,vishakapatnam in which minimum cut off required for sc category is 50 percentile but that the chances are less.
