Hi luqman.
Yes it may happen that ur result may not come due to single mistake in omr but there is great possibility that u will get Ur result because other information are more imp. Especially your roll no. ,Name , dob which you have filled correct .
but till then ,until when, result is not coming ,don't worry much & hope for the best .
If by chance it doesnt come,then you can call to helpline centre by going through neet ug website & ask for solution .
Thanks...
