is there any negative marks for wrong response

Greetings
Of course there is a negative marking scheme in NEET UG
For every right answer you will be awarded 4 marks while for
every wrong answer you will be losing 1 mark. So it's +4 for
a right answer and-1 for a wrong answer. Please note that
for the wrong answer there is no other marks awarded. For
answers left unanswered you will not be awarded any marks
Also there is no negative marking scheme for questions left
answered
So it is advisory to be sure about what you're marking in
your answer sheet. A great deal of negative marking may
significantly lower your marks and consequently your rank.
I hope this piece of information comes to be handy
