What is my expected bihar rank if my all india rank is 13211. General category rank - 8050 ?

Hello aspirant. First if all congratulation on your wonderful rank.
Now, lets come to your question. So, according to your question the answer is not something easy to answer.
First thing first cutoff changes almost every year and so is the competition.
It is very difficult to say something up in the air but by now neet results are out.
However, one thing is possible in this situation. You can always use state quota.
I hope you may find this answer helpful.
All the very best.
