Open the Calculator
Go to the main calculator on the homepage
Navigate to the GWA Calculator homepage. The calculator is placed at the very top of the page — you don't need to scroll to access it. You'll see three default subject rows already filled in. You can modify these or start fresh by clicking the Reset button.
Tip: On mobile, the calculator is fully responsive. All inputs and dropdowns are touch-friendly and easy to use.
Enter Your Courses
Fill in each subject row with the required information
Each subject row has three fields: Course Code (optional), Units (required, 0.25–12), and Grade (select from PH scale dropdown).
Add or Remove Courses
Customize the number of subjects
To add another subject, click the + Add Course button. To remove a subject, click the trash icon on the right side of any row. The calculator requires at least one subject.
Important: Do NOT include subjects like PE, NSTP, SP/Thesis, HK, or Military Science unless your school specifically includes them in GWA computation.

Understanding the GWA Formula
Example: You have 3 subjects:
| Course | Grade | Units | Grade × Units |
|---|---|---|---|
| Math 11 | 1.50 | 4 | 6.00 |
| Eng 1 | 2.00 | 3 | 6.00 |
| Phys 71 | 1.75 | 4 | 7.00 |
| Total | 11 | 19.00 |
GWA = 19.00 ÷ 11 = 1.73 (Very Good)
