Hey!

AHSEC does have grace marks policy. Following are the rules for giving grace marks in class 12th examination : 

• The grace marks will be limited to 5%,4% and 3% of maximum marks for A,B and C grades respectively.
• The authorities will first prefer to pass you in the subject and provide minimum D+ grade atleast. Then, preference will be for increasing grade of subject in which you scored the least.
• The condition with highest grace mark only will be considered.
• 25% grace marks for mentally retarded and hearing impaired.
• If a student appears for lesser number of papers only, the percentage will be calculated based on the number of papers appeared for. 
• Grace marks will not be given for subsequent appearances.
• The individual grace marks will not be shown in the certificate separately.
• Candidates coming within the limit of moderation after the award of grace marks will also be given the benefit of moderation and grace marks.
• Grace marks for sports and games are awarded on the basis of the recommendation of the DPI,for NSS on the basis of the recommendation of the State Coordinator, NSS and that for NCC on the recommendation of NCC Directorate.

Hope it helps!
