One of my friends was a student in SPPU so I asked him about the policy for giving grace marks there. He mentioned a few scenarios where his batchmates received grace marks

• One of them received grace marks in an exam in which he actually scored 36. This course was from the 3rd semester. So he probably got grace marks because he had cleared all the subjects in the previous semesters.
• In the third year, he again secured 39 marks in DME and because he already has received grace marks before, he failed in the subjects. So once you get grace marks, it’s impossible to get it again.
• Another batchmate got a backlog when he was in the last semester of Engineering. He had got an offer from a good university for MS and therefore requested the university to give him grace marks although he had some backlogs in his 2nd and 3rd years the university granted him grace marks and he was awarded the degree.

So, to avail of grace marks at SPPU, one needs to have a good academic record. Usually, the limit of maximum marks is less than 10. 

Grace marks are a maximum of 10 marks, i.e. 1 percent aggregate for failed subjects, e.g. 30 out of 100 in one subject and remaining subjects passed, then 10 marks grace.

• If you fail only one course while passing all others, your deficiency of marks in that subject may be excused by not more than 1% of the examination's aggregate marks or 10% of the total number of marks in that head of passing in which you are failing, whichever is less. 
• Condonation, on the other hand, should be limited to a maximum of 10 points in either one or both of the passing categories.
• Condonation of deficiency of marks can be shown in the Statement of Marks in the form of asterisk and Ordinance number.
• Provided that this condonation of marks is concurrent with the rules and guidelines of professional statutory bodies at the India level such as AICTE, MCI, Bar Council, CCIM, CCIII, NCTE, and so on.
• If you fail in one head of passing but pass in another head of passing in the same subject, you are entitled to the benefit of the Condonation in both heads, if necessary, up to the maximum amount of Condonation allowed.
• If a deficiency in marks is excused, your class/grade in the relevant examination will be determined based on the actual marks earned.

Only one examination of a single course may be awarded the advantage of more than one Ordinance. The benefits of the above-mentioned Ordinances may be granted to candidates who are taking the test with a backlog and/or exemption if such an exemption/backlog system is available.
