Common GWA Calculation Mistakes Students Make (Avoid These)
A number of students in the Philippines struggle when calculating their General Weighted Average. Even simple and minor GWA Calculation mistakes can falsify the results, which would eventually affect scholarships, honors, or other academic achievements.
Think of it like this: your father gives you money; you spend it unwisely; your whole budget gets affected. Same logic here, one wrong move, and your GWA gets messed up.
in this article, you will be learning the most common GWA calculation mistakes and how to avoid them.
What is GWA and Why Accuracy Matters
General Weighted Average or GWA is the average of your total grades, adjusted by credit units
It is used for:
- Latin Honors (Cum Laude, etc)
- Academic assessment
- Scholarships
Even a small miscalculation can change your academic position.
Top 10 Common Mistakes GWA Calculation Mistakes

1. Ignoring Credit Units
This is the most common mistake students make: they treat all subjects equally. The correct thing to do is that those subjects with higher units should have more weight.
Example:
Maths (5 units) is not equal to PE (2 units). If you ignore this your GWA will be completely wrong.
2. Using Simple Average Instead of Weighted Average
Many students take this approach (Grade 1 + Grade 2 + Grade 3) / Total Subjects. This is wrong. It uses (Grade X Units)/Total Units.
3. Entering Wrong Grades
A very simple but quite common mistake is to input wrong grades, which could be due to a typo. Mixing grades or forgetting the updated grades. Always double-check your inputs.
4. Mixing Different Grading Systems
Some students confuse:
- 1.00 – 5.00 scale
- Percentage
- GPA Scale
Mixing them alters the result; always stick to one system like that of The University of The Philippines (General Weighted Average Scale). Find out yours by using our General Weighted Average Calculator.
5. Forgetting Failed Subjects
Some students ignore failed subjects, thinking it won’t matter. But the truth is, it does matter. Failed grades like closer to 5.00 or 5.00 itself affect your GWA quite heavily.
6. Not including All Subjects
Just like forgetting one person when counting family members, missing even one subject will alter the real value of GWA
7. Wrong Total Units Calculation
Even if all else is correct, the wrong total of units = wrong final answer. Always recheck, even when you are sure, because there is always a chance of human error. Make sure to verify your total credit units and number of subjects.
8. Rounding Off Too Early
Sometimes students round off their grades earlier than they should, even before the final calculation. It results in inaccurate results. Solution: only round off the final grade
9. Using Incorrect Formula
Some students guess the formula or use random known online methods; they mess up their grade. Always use the correct formula:
GWA = Σ(Grade × Units) ÷ Σ Units
10. Relying on Unreliable Calculators
Not all online calculators are accurate. Some of them ignore units, have poor UI which ruins the UX, or some of them are using wrong formulas. Always use a trusted GWA Calculator like ours.
