Hi Candidate,

Grace marks are generally those marks which are alloted to students when their is some error in the Question paper such as wrong data, Incomplete information or Printing mistake.

The toughness of the paper is not a criteria for Grace marks but yes, it impacts the cut-off very well. The toughness of the paper implies that the cut-off is generally lower than the previous years, si which means that the Closing Ranks might get lowered.

Hope that this answer helps you. Thank You.
