Dear Abhay, AIIMS has its colleges across India in New Delhi, Patna, Bhopal, Bhubaneshwar, Jodhpur, Raipur, Rishikesh, Nagpur and Guntur. It also plans to set up colleges at 9 places. Now AIIMS conducts entrance exam for these colleges. Now the cut off changes every year depending upon the no. of candidates who attended the exam and the difficulty of the exam. If the exam is difficult, then the cut off marks will be lesser. The cut off marks are also different for general category, SC/ST/PWD and its also different for each college across India.
