## What is GWA?

GWA, or general weighted average, is the typical averaging system used in the Philippines for grading a college or university student's academic performance. Assessing a student's overall performance requires consideration of the weight of each course or subject taken.

We quantify the weight of each course depending on its difficulty or importance using the equivalent credits or units they contribute to the overall curriculum of a degree. Generally, major courses weigh more than minor courses and are, therefore, worth more units.

## How to compute GWA in college

We can use the general formula to find the weighted average of different numerical values to compute the general weighted average. You can learn more about weighted averages in our weighted average calculator.

Since we're dealing with grades and units, here is our general weighted average formula where the variables represent the course grades and course units we want to consider:

$\small \text{GWA} =\frac{\sum_{i=1}^n (g_i\times u_i)}{\sum_{i=1}^n u_i}$

where:

• $\text{GWA}$General weighted average;
• $g_i$Grade of each course or subject;
• $u_i$Units or credits of each course;
• $i$Index of the summation where its value ranges from $i = 1$, $i = 2$, up to $i = n$; and
• $n$Total number of courses considered in the calculation.

Let us consider an example in the next section of this text.

## Example of how to compute general weighted average in college

As an example, let's say we want to take the general weighted average of the course grades given in the following table:

Course number

Course units

1

3

1.00

2

1

1.25

3

5

1.50

By following our GWA formula, we know that we have to take the sum of the products of the course grades and their corresponding course units and divide that sum by the total number of course units. In equation form, we express that as shown below:

\scriptsize \begin{align*} \text{GWA}\! &=\frac{\sum_{i=1}^n (g_i\times u_i)}{\sum_{i=1}^n u_i}\\[1.2em] &=\frac{(1.00\! \times\! 3)\! +\! (1.25\! \times\! 1)\! +\! (1.50\! \times\! 5)}{3 + 1 + 5}\\[1.2em] &=\frac{(3.00) + (1.25) + (7.50)}{9}\\[1.2em] &=\frac{11.75}{9}\\[1.2em] &= 1.30555\\[0.5em] &\approx 1.31 \end{align*}

That's how to compute the general weighted average. However, note that the universities and colleges in the Philippines use different grading systems. Others use a grade-point scale where the highest grade is 1.00, while some have 4.00 as their highest grade. Other institutions follow the GPA grading system used in the United States. Nevertheless, the same process of calculation holds.

For letter grading systems, we first take their equivalent grade point system before we proceed with the computation. Some universities use this letter grade-to-grade-point scale equivalence table:

4.0

A

3.5

B+

3.0

B

2.5

C+

2.0

C

1.0

D

0.0

F

Some use this equivalence table:

In the next section of this text, we'll show you how to use our GWA calculator, which you can use for any grading system used in the Philippines.

## How to use this GWA calculator

Using this GWA calculator is as simple as 1, 2, and 3.

2. Select the grade and enter the units of your first course or subject you want to consider in the calculation.

3. Repeat step 2 for your other subjects. You can enter up to 30 courses in this tool.

That's it! Our GWA calculator will instantly display the general weighted average of the course grades you entered.

## FAQ

### How do I calculate my GWA?

To calculate your GWA, or general weighted average, if, let's say, on a math course of 5 units, you got a grade of 1.50; on a science course of 3 units, you got 2.25; and on an art course of 3 units, 1.00:

• For math: 5 units × 1.50 = 7.50;

• For science: 3 units × 2.25 = 6.75; and

• And for arts: 3 units × 1.00 = 3.00.

2. Sum of those products to get:

7.50 + 6.75 + 3.00 = 17.25.

3. Divide that sum by your total number of units to get your GWA:

17.25 / (5 + 3 + 3) = 17.25 / 11 = 1.56818 ≈ 1.57.

### How is overall GWA calculated?

We calculate the overall GWA of a college student by adding all the products of all courses' grades and their respective number of units; then, we divide that sum by the total number of units the student took throughout their university stay.

### What is the passing GWA in the Philippines?

The passing general weighted average in the Philippines depends on the grading system used by the university. Universities that use a grade-point scale of 1.00 to 5.00, where 1.00 is the highest, usually consider 3.00 as their passing GWA. On the other hand, institutions that use a 4.00 to 1.00 grade-point scale consider 1.00 as passing.

### What is the equivalent GPA of a 1.00 GWA?

A general weighted average of 1.00 on a grade-point scale of 1.00 to 5.00 is equivalent to a GPA of A+. However, for a 1.00 to 4.00 grade-point scale (where 4.00 is equivalent to A+), we now consider a GWA of 1.00 to be equivalent to a GPA of D.
