Gagan, this is the first time that AIIMS is conducting its admissions its MBBS course based on NEET score. So it is difficult to predict as to how might the cut offs be. And because the admissions will happen through All India Counselling, one can assume the cut offs to be quit high. Cut offs depend on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. So you will need atleast 650-675 for a seat in AIIMS Delhi.
