1. What is the Grade Average Percentage?

The Grade Average (GA) percentage is a measure of academic performance calculated by summing all grades and dividing by the number of grades, then multiplying by 100 to get a percentage.

2. How Does the Calculator Work?

The calculator uses the Grade Average formula:

Where:

• \( GA \) — Grade Average percentage
• \( g_i \) — Individual grades
• \( n \) — Number of grades
• \( \sum \) — Summation of all grades

Explanation: The equation calculates the arithmetic mean of all grades and converts it to a percentage.

3. Importance of Grade Average

Details: Grade Average is crucial for academic assessment, determining class rankings, scholarship eligibility, and overall academic performance tracking.

4. Using the Calculator

Tips: Enter grades as comma-separated values (e.g., 85,90,78). All values must be between 0 and 100. The calculator will ignore invalid entries.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between GA and GPA?
A: GA is a simple percentage average, while GPA (Grade Point Average) typically uses a 4.0 scale with weighted letter grades.

Q2: How should I enter letter grades?
A: Convert letter grades to their percentage equivalents before entering (e.g., A = 90-100, B = 80-89, etc.).

Q3: Does this calculator handle weighted grades?
A: No, this calculates a simple average. For weighted averages, you would need to adjust grades before entering.

Q4: What if I have incomplete/missing grades?
A: Either exclude them or enter a placeholder value (like 0) if that's your school's policy.

Q5: How precise is the calculation?
A: The calculator shows results rounded to 2 decimal places for clarity.
