Hello Aspirant,

See generally for such difference authorities give grace marks of 2-3 marks so that the candidate can pass at least but it is not for sure therefore now it all depends upon luck and the nature of teacher whoever will be checking your answer sheet, but there are much chances that the teacher might pass you with grace marks until an unless it is any internal test whose marks are not to be added in the final result.

I hope this information helps you.

Good Luck!!
