CBSE Class X Result 2010 – How to Calculate Percentage
Today, CBSE Board, India declared class X result for year 2010. But here is a catch – this year they changed the rating from numbers to grades. Most of the students are apparently confused how to get percentage from their GPA.
How to convert CGPA to Percentage
Here is the simple method to convert GPA into percentage:
Percentage = 9.5 × CGPA
Example:
CGPA = 6.8
Percentage = 9.5 x CGPA = 9.5 x 6.8 = 64.60%
The percentage calculated by this manner is the overall percentage.
How to convert GP to Percentage
Here is the simple method to calculate percentage from GP:
Percentage = 9.5 x GP
Example:
GP = 06
Percentage = 9.5 x 6 = 57.6%.
The percentage calculated in this manner is the percentage in that particular subject.
SUBJECT WISE GRADE POINT:
| Marks Range | Grade | Grade Point | Percentage |
| 91-100 | A1 | 10 | 95% |
| 81-90 | A2 | 9 | 85.5% |
| 71-80 | B1 | 8 | 76% |
| 61-70 | B2 | 7 | 66.5% |
| 51-60 | C1 | 6 | 57% |
| 41-50 | C2 | 5 | 47.5% |
| 33-40 | D | 4 | 38% |
| 21-32 | E1 | - | - |
| 20-0 | E2 | - | - |
The magic number 9.5:
The number 9.5 in the percentage calculation is not a magic number. This is derived using following formula:
Percentage = (10 x GP) - (GP/2)
Percentage = GP(10 – 1/2)
Percentage = GP(9.5) = 9.5 x GP.
Hope this will clear students confusion.
