How to Compute GWA in Senior High School: A Comprehensive Guide

The Grade Weighted Average (GWA) stands as a pivotal metric in the academic journey of Senior High School (SHS) students, serving as a comprehensive reflection of their overall scholastic performance. The process of computing GWA, often facilitated by a GWA calculator, involves assigning weights to grades based on the respective credit units of each subject. This guide is crafted to offer students, parents, and educators a lucid comprehension of the intricacies involved in calculating GWA throughout the Senior High School experience.

Comprehending GWA:

GWA serves as a numerical representation of a student’s academic accomplishments, manifested as a weighted average of their grades across diverse subjects. This computation takes into account both the numerical values of the grades and the credit units associated with each subject. Such an approach ensures a more precise evaluation of a student’s overall performance, accommodating variations in the difficulty and significance of distinct courses.

Grade System and Corresponding Values:

The Senior High School employs a numerical grading system, typically ranging from 0 to 100, accompanied by corresponding letter grades. Each letter grade is intricately linked to a specific numerical equivalent.

The following is a common conversion table:

GradeDescriptionNumerical Range
AExcellent90 to 100
BVery Good80 to 89
CGood75 to 79
DFair70 to 74
FFailedBelow 70

Defining Credit Allocation:

Credit units serve as a measure of the significance and complexity assigned to each academic subject. Typically, subjects with more extensive academic requirements are granted higher credit units, reflecting their broader scope. For example, a science-oriented course might carry more credit units compared to an elective with a narrower focus.

To derive the Grade Weighted Average (GWA), it is necessary to multiply the grade achieved in each subject by its corresponding credit units.

Formula for GWA Computation:

The GWA is derived through the following formula:

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


  • \( \sum \) denotes the sum of
  • \text{Grade} represents the numerical equivalent of the letter grade
  • Credit Units} refer to the assigned weight of each subject

Step-by-Step Guide to Calculating GWA:

Use the transmutation table to transmute the initial grade and obtain the quarterly grade.

1. Collect Your Grades and Credit Units:

  • Gather the grades obtained in each subject.
  • Identify the credit units assigned to each subject.

2. Convert Letter Grades to Numerical Equivalents:

  • Consult the grading system to determine the numerical equivalent of each letter grade.
  • For instance, if an ‘A’ is achieved in a subject, its numerical equivalent is 90.

3. Multiply Grades by Credit Units:

  • Multiply the numerical equivalent of each grade by the corresponding credit units for each subject.
  • Repeat this process for all subjects.

4. Sum the Results:

  • Add up all the products obtained from the multiplication in the previous step.

5. Sum the Credit Units:

  • Add up the credit units assigned to all subjects.

6. Apply the GWA Formula:

  • Utilize the GWA formula to calculate the overall Grade Weighted Average.

7. Interpret the GWA:

  • Your GWA serves as a comprehensive indicator of your overall academic performance throughout Senior High School.

Tips & Tricks:

Stay Informed about Your Academic Progress:

Regularly monitor your grades throughout the academic year to pinpoint areas for potential improvement.

Grasp the Significance of Credit Units:

Understanding the allocation of credit units to each subject helps you prioritize your efforts effectively.

Embrace Support When Necessary:

In the face of challenges with specific subjects, don’t hesitate to seek assistance from teachers, classmates, or tutors.

Strategically Manage Your Course Load:

Take into account the credit units when selecting your courses, ensuring a well-balanced workload.

Value Electives:

Despite having fewer credit units, excel in elective courses as they contribute positively to your overall GWA.


How is Senior High School GWA calculated?

GWA is computed by assigning weights to subject grades based on unit value, multiplying them, and dividing by the total units.

What is the significance of quarter grades in GWA computation?

Quarter grades, each with a 20% weight, contribute to the overall GWA, providing a holistic assessment.

Can I compute my GWA if I have incomplete grades in Senior High School?

Incomplete grades affect GWA calculations. You may need to wait for the completion of the subjects for an accurate GWA.

How does the GWA impact college applications?

GWA is a crucial factor in college admissions, reflecting academic performance and potential.

Is the GWA calculation the same for all Senior High School tracks?

GWA computation is generally uniform, but specific tracks may have additional criteria or subject requirements.

What happens if I retake a subject in Senior High School?

If you retake a subject, both the original and retake grades may be factored into the GWA calculation, depending on your school’s policy.

Are non-academic factors considered in GWA computation?

GWA is primarily based on academic performance, but some schools may incorporate non-academic factors in their evaluation process.

Can extracurricular activities influence my GWA in Senior High School?

While GWA is based on academic performance, active involvement in extracurricular activities might be considered in holistic assessments by some institutions.

Is there a standardized GWA scale for Senior High School?

GWA scales may vary among schools, but they commonly use a 1–100 scale with corresponding letter grades.

What should I do if there’s an error in my GWA computation?

If you notice a discrepancy in your GWA, promptly bring it to the attention of your school’s registrar or administration for resolution.


The process of calculating the Grade Weighted Average in Senior High School is methodical, involving a clear understanding of the grading system, credit units, and the application of a straightforward formula. By following the comprehensive step-by-step guide presented in this article, students can accurately compute their GWA, gaining valuable insights into their overall academic performance. Regularly monitoring grades, seeking assistance when needed, and maintaining a balanced course load are essential elements in achieving a favorable GWA and, ultimately, a successful Senior High School journey.
