Hi Rishab 

Any candidate is eligible to sit in AIIMS entrance exam if he/she has passed out class 12th board exam or any other exam equivalent to it from some recognized board or university. Candidates appearing for these exams are also eligible to take the entrance exam.

So being a NIOS student ,ofcourse you can appear in the exam..

Good luck
