The CGPA is the average of Grade Points obtained in all the subjects excluding additional 6th subject as per Scheme of Studies.

An indicative equivalence of Grade Point and Percentage of Marks can be assessed as follows:

Subject wise indicative percentage of marks = 9.5 x GP of the Subject.

Overall indicative percentage of marks = 9.5 x CGPA

The above formula given by CBSE to convert grades into marks and percentage is only an approximation and not exact.

According to CCE pattern, it is an overall indicative percentage of marks.

Multiply the CGPA with 9.5 or use the above calculator to get the indicative percentage.

The Board took the result of the last five years and calculated the average marks of all candidates who had scored between 91 and 100. That average turned out to be close to 95 marks. Since the equivalent Grade Point for the 91-100 band (A1 grade) of marks is 10, it then divided the average result of 95 by 10. The result is 9.5.
