What is GWA (General Weighted Average)?

The General Weighted Average (GWA) is a numerical representation of a student's academic performance across all courses, weighted by the credit units of each subject. Unlike a simple average, the GWA accounts for the varying importance (credit hours) of different courses. For example, a 3-unit math class impacts the GWA more than a 1-unit elective. It is widely used in educational institutions to evaluate eligibility for honors, scholarships, or program requirements.

How to Calculate GWA (General Weighted Average)

To calculate GWA, multiply each course’s grade by its credit units, sum these values, and divide by the total number of credit units. The formula is:

\[ \text{GWA} = \frac{\sum (Grade \times Credits)}{\sum Credits} \]

Example: Suppose a student has the following grades:

• Math (3 units): 1.5
• Science (4 units): 2.0
• History (2 units): 1.0

Calculation:

\[ \text{GWA} = \frac{(1.5 \times 3) + (2.0 \times 4) + (1.0 \times 2)}{3 + 4 + 2} = \frac{4.5 + 8.0 + 2.0}{9} = \frac{14.5}{9} \approx 1.61 \]

A lower GWA indicates better academic performance (e.g., 1.0 is the highest in many systems).

While manual calculation is straightforward, a GWA calculator simplifies the process, especially for large datasets. These tools automate the formula, reducing errors and saving time. Users input their grades and corresponding credit units, and the calculator instantly computes the weighted average. This is particularly useful for students planning their academic load or tracking their progress toward graduation requirements.

Understanding your GWA helps in setting academic goals and identifying areas for improvement. Whether calculated manually or digitally, it remains a key metric in educational success.
