Dekhiye Aisa Nahi Hota isaka Example Hai ki maine neet 2017 me exam pressure ki wajah se ek nahi 3-3 Bubbles Galat Bhara Tha But Result Aaya.Right Now main IMS Varanasi Se MBBS Kar Raha Hu.But in Boards Isase Koi fark nahi padata ki aapne bubbling kya ki hai..bas roll number wording aur Numerals me sahi ho,lekin isake galat hone par bhi result aa jaate hai kyuki us wakt centre se student ka sara credential nikala jaata hai.

HELLO

It will be a big trouble. don't ever do that. Each student get enough time to write their credentials.

It also invigilator responsibility. but it will not affect the invigilator if it happens. it will totally affect the student.

now coming to the question , if it happen then you will be counted absent even if you fill bubbles correctly. also they not provide you extra OMR.

You also take care of those things.

That's it.

HOPE THIS HELP!
