what will be the maximum all india rank would require to get into aiims MBBS and please tell marks also

dear jahanavi 
aiims have only 670 seats , from that also most of the seats are reserved for caste candidates . 
so, u need to have a rank within 1000 to get into any of the 6 aiims . 
last year it went upto 1200 rank but every year that changed , so, 1000 will be a safe side . 
and for that u need to score around 130-160 in aiims mbbs exam .
