Hello Rahul,
Considering optium difficulty and the previous year trends you may need to get a rank of under 200-300 or a percentile above 99.80.
And if you are thinking of AIIMS Delhi then an AIR of under 50 or a percentile of 99.987 is necessary to have a chance.
Also notice I'm talking for the general category and also the above mentioned ranks are the closing ranks.
