Dear Anjana

With AIR 2455 and belonging to UR, the chances are low as the last year cut off was AIR 1353 for AIIMS Mangalagiri but there can be still some hope as 6 new AIIMS has been introduced this year and 81 seats(UR) have been incremented which will make some place for getting a seat upto point(doesn't guarantees you a seat). However, the merit list changes every year, only on that basis the admission is done.

All the best.
