Example: Calculate CGPA from Marks
Let’s assume a student has obtained the following marks and grade points in five subjects:
| Subject | Marks | Grade Point |
|---|---|---|
| Mathematics | 85 | 9 |
| Science | 92 | 10 |
| English | 76 | 8 |
| Hindi | 67 | 7 |
| Social Science | 81 | 9 |
Total Grade Points: 9 + 10 + 8 + 7 + 9 = 43
Total Subjects: 5
Therefore, the student’s CGPA is 8.60.
Percentage Conversion:
Based on this example, a CGPA of 8.60 is approximately equal to 81.7% when a 9.5 conversion factor is used.
