Hello Aman,

Yes, of course, if grace marks are given it will be given for all sets of paper as the toughness or trickiness of the paper is not set based it is year based and if in some year the question paper is tough and ticky then all of the paper sets are so for that subject.

Now, according to the official announcement "Board will definitely keep students' future and career in mind and decided to appreciate 8 marks for these respected sets as grace only if a student has even tried to attempt any of these questions, marks will be given. We found Set-III question paper not so difficult with almost NCERT questions but somewhat lengthy. Marking scheme will be lenient and student-centered."

Don't worry.
