Hello Harsh,

Well its not conformed that weather cbse will provide grace marks this time or not. Also its depend on paper, if exam paper comes very tough than chances of grace marks increases.

But you should work hard for scoring good marks.

All the best.

Grace marks definitely provided but depends from which board you hav ecomoleted 12th grade. 

All boards hav eown protocol to be followed. 

For CNSE board grace marks related official announcement not made, and hence difficult to predict.
