Hello,

Grace marks in the compartment exam depend on your board's policy.

For CBSE, if you are failing by a few marks (usually 1–5 marks), the board may give grace marks to help you pass.

So, if the passing marks are 23 and you scored 18, it’s a gap of 5 marks. There is a chance you may get grace marks, but it is not guaranteed. It depends on board rules and evaluation.

Hope it helps !
