Dear Kesav
Have you checked answer key of NEET 2017?

According to experts from ALLEN Kota and Aakash Institute, there are bonus marks from Physics, Chemistry, and biology.

1 question in Physics (LCR circuit) had no correct option. The correct answer was 4 amperes. So 4 marks bonus.

Moreover 3 questions in biology had 2 correct options. These should either be bonus or have 2 answers in official key (preffered).
And some of them are saying that officially announced and some of them or not. So according to my view,  definitely, they will take action against this. So, don't worry.
All the best.
