How CGPA is Calculated?
CGPA (Cumulative Grade Point Average) is calculated based on the grades obtained by a student in different subjects or courses over a specific period, such as a semester or an academic year. The CGPA system is commonly used in educational institutions to assess a student's overall academic performance.
Here's the general process of how CGPA is calculated:
- Assigning Grade Points: Each subject or course is assigned a grade based on the student's performance. The grading system may vary depending on the educational institution or board. For example, the grades could be A, B, C, D, E, F, or they could be represented in a numerical scale like 10, 9, 8, 7, 6, etc. Additionally, each grade is associated with a specific grade point. Higher grades are usually associated with higher grade points.
- Calculating Grade Points: For each subject, the grade points earned by the student are multiplied by the credit hours (if applicable) of that subject. This gives the "Quality Points" for that subject.
- Calculating Cumulative Grade Points: The total Quality Points earned in all subjects are added together to get the Cumulative Grade Points.
- Calculating CGPA: To calculate the CGPA, the Cumulative Grade Points are divided by the total number of credit hours (if applicable) of all the subjects. This gives the average grade point, which is the CGPA.
The CGPA provides a standardized measure of a student's academic performance, taking into account both the grades and the credit hours (if applicable) of each subject. It is a useful tool for universities, colleges, and other educational institutions to evaluate students' overall progress and to make fair comparisons between students from different educational systems and boards.
Sure! Let's consider an example to illustrate how CGPA is calculated:
Suppose a student has completed three subjects in a semester with the following grades and credit hours:
- Subject 1: Grade - B, Credit Hours - 3
- Subject 2: Grade - A, Credit Hours - 4
- Subject 3: Grade - C, Credit Hours - 2
Now, let's assign grade points to each grade:
- A: 4.0
- B: 3.0
- C: 2.0
Step 1: Calculating Grade Points for each subject:
- Subject 1: Grade B (3.0 grade points) * 3 (credit hours) = 9.0 Quality Points
- Subject 2: Grade A (4.0 grade points) * 4 (credit hours) = 16.0 Quality Points
- Subject 3: Grade C (2.0 grade points) * 2 (credit hours) = 4.0 Quality Points
Step 2: Calculating Cumulative Grade Points:
Total Quality Points = 9.0 + 16.0 + 4.0 = 29.0
Total Credit Hours = 3 + 4 + 2 = 9
CGPA = Total Quality Points (29.0) / Total Credit Hours (9) = 3.22
So, the CGPA for this semester is 3.22. The CGPA provides an average measure of the student's academic performance in that particular semester.
How to Convert CGPA to Percentage?
The formula to convert CGPA to percentage is as follows:
Percentage = CGPA * Conversion Factor
The formula to convert CGPA (Cumulative Grade Point Average) to a percentage is relatively straightforward. In most cases, you can use the following formula:
Percentage = CGPA × 9.5
Here's what each part of the formula means:
CGPA: This is your Cumulative Grade Point Average, which is usually on a scale of 10. It represents your overall academic performance.
9.5: This is a constant multiplier. It's used because the typical percentage system has a maximum value of 100, while the CGPA system has a maximum value of 10. So, to convert from one scale to another, you multiply the CGPA by 9.5.
By using this formula, you can convert your CGPA to the equivalent percentage. For example, if your CGPA is 8.0, you can calculate your percentage as follows:
Percentage = 8.0 × 9.5 = 76.0%
So, in this case, your percentage would be 76.0%. This formula is commonly used in educational institutions and job applications where the percentage system is the standard measure of academic performance.
