To take the admission in AIIMS you need to give AIIMS entrance exam. And based on your NEET score the chances are less to get a seat for MBBS in Gov & private colleges. So I would suggest you to prepare again for the exam.

Been there done that, nothing is impossible but still you can't expect aiims seat when you have scores like this..
Consider it in this way
You have almost 11 months to study the whole syllabus that cbse wanted you to study in 2 years . Now I hope you get what I'm trying to say nothing is impossible with proper planning but experience speaks man I have done all that still got nothing !

Drop one year and prepare at home........revise and memorize   .......
