CBSE Class 10 results are to be announced soon. From the year 2011, CBSE, as per CCE (Continuous & Comprehensive Evaluation) system of evaluation produce the result in CGPA format.

CGPA (Cumulative Grade Point Average) is the average of grade points achieved in all subjects excluding the additional 6th subject as per Scheme of Studies.

As per the grading system, minimum qualifying grade for passing the board exam is grade D. Students who will score E1 or E2 grades, will have to sit for re-examination within a month after the results announced.

Marks Grades Grade Point
91-100 A1 10
81-90 A2 9
71-80 B1 8
61-70 B2 7
51-60 C1 6
41-50 C2 5
33-40 D 4
21-32 E1 0
20 & below E2 0

How to calculate percentage from CGPA?

To convert CGPA into percentage, multiply the CGPA with 9.5 to get the overall indicative percentage.

You might ask, why multiply with 9.5 only. Your senior toppers of CBSE board have contribution in it. Here’s why. The Board analyzed the result of 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.

The board disclaims that the percentage is only approximation and not exact percentage.

Let’s take an example to convert CGPA to GPA:

Suppose the student scored

Subject 1 – 9

Subject 2 – 10

Subject 3 – 9

Subject 4 – 7.5

Subject 5- 8

So, now the sum of the GPs will be : 9+8+7.5+9+10 = 43.5

Dividing the sum of all the GPs with 5 will be 43.5 / 5 = 8.7

8.7 is the overall indicative percentage of marks

To find out the approximate percentage of marks, multiply the CGPA with 9.5

that is, 9.7 x 9.5 = 82.65

How to convert CGPA to Percentage?

So an indicative equivalent percentage of the grade point can be calculated as:

Subject wise percentage =  Grade point (GP) obtained by the student x 9.5

And the overall percentage of marks = 9.5 x CGPA
