Hello  Deepak (dubey ji)

My father is also in paramilitary. But did not getting merit list if central pool quota

You should be within the the top 50 percentil, that is qualify the NEET exam to be eligible for the central counselling.

Marks in not always a deciding number but perecentile is since it is upon the percentile  which is the estimate of how many people are ahead of us.

You must qualify within top 50 percentile for eligibility

All the best!
