What if a class 12 board answer sheet gets torn or wet after the?
If the teacher is linient enough, he might give you extra time to dry the sheets or write a page or two again or you are doomed! Mostly invigilators are good though, I remember during my 10th boards, I couldn't tie up the sheets and the bell rang and I still wasn't able to tie it up, the invigilator came and helped me out (after everyone else had left) and a part of my copy had gotten torned down as well. But I don't think it affected my marks. (or maybe it did as I definitely scored less than I was expecting). Anyway it really is an unfortunate situation and that's why you should keep water bottles away from your answer sheets.
