Hello aspirant,

For passing board exams the minimum percentage to get is 33%. Since maths paper is out of 100 marks so you need to get at least 33 out of 100 to pass the exam. It totally depends on the evaluator who is checking you paper, if the evaluator is strict they probably won't give but if the evaluator is lenient then you might have a chance. Grace marks are given in board exams depending if you wrote enough. At the max the evaluator can give 3-5 grace marks but more than that it is not possible.

Don't lose hope.

All the Best!

Thank you.
