Hello Renu,

The scholarship exams like NTSE, KVPY are completely different from the AIIMS or any other medical entrance exam. Preparation of either might help you in appearing for the other exams. Otherwise, both are independent exams.

Good Luck!

No, it is not necessary  to qualify NSE Olympiads or any other examination. As in AIIMS examination only your marks which you get in the  competitive examination are useful. AIIMS is not at all correlated with NSE or KVPY Olympiads .It is just that, if you have studied for NSE you will have extra knowledge which will be helpful to you in the future.But for this AIIMS, you have to  score atleast  minimum marks in the competitive examination to get entry in the medical college .
