Dear Nitin,

According to the previous year's cut off you chances of getting AIIMS Delhi in this rank is very mild,almost nil. 

The cut off for AIIMS Delhi for obc category was 236  in obc category and 53 is general category.Your rank is far behind the last year's cutoff.But you would surely get into other AIIMS colleges with this rank.

Still hope for the best.ALL THE BEST FOR YOUR COUNSELLING!!
