Hi

Yes, board examinations do provide step marking provided your steps are correct.

For example,

If there is a question of 5 marks in board examination and you solve it and own mistakes are correct but due to a mistake in the last step you reach to a  wrong answer. Then in that case you will get at least 3 out of 5 marks.

Actually , answer sheets of board examinations are checked according to marking scheme and marking scheme mentions step wise marks so yes step marking is provided in board examination so you don't need to worry about it.

Thankyou
