CGPA stands for Cumulative Grade Point Average. It is a measure of a student's overall academic performance over a specified period, typically the entire duration of their academic program. CGPA is calculated by taking the average of grade points obtained in all the courses, weighted by the number of credits for each course. It provides a comprehensive view of a student's academic achievements and is often used by educational institutions, employers, and scholarship committees to assess qualifications.
CGPA is calculated by converting each course grade into grade points (usually on a 4.0 or 10.0 scale) and then taking a weighted average based on the course credits. The formula is:
CGPA = (Σ (Grade Points × Course Credits)) / Σ Course Credits
Letter | Percentage | 4.0 Scale |
---|---|---|
A+ | 90-100 | 4.00 |
A | 85-89 | 3.75 |
A- | 80-84 | 3.50 |
B+ | 75-79 | 3.25 |
B | 70-74 | 3.00 |
B- | 65-69 | 2.75 |
C+ | 60-64 | 2.50 |
C | 55-59 | 2.25 |
D | 50-54 | 2 |
F | 0-49 | 0 |
Let's assume the following values:
Using the formula:
\[ \text{Total Grade Points} = (3 \times 4) + (4 \times 3) + (2 \times 2.5) = 12 + 12 + 5 = 29 \]
\[ \text{Total Credits} = 3 + 4 + 2 = 9 \]
\[ \text{GPA} = \frac{29}{9} \approx 3.22 \]
The calculated GPA is approximately 3.22.
