1. What is GPA Calculation?

GPA (Grade Point Average) is a measure of academic achievement calculated by dividing the total grade points earned by the total credits attempted. The average percentage is the mean of all your grades.

The calculator uses the following formulas:

Where:

• \( g_i \) — Individual grade percentages
• \( c_i \) — Credit hours for each course
• \( n \) — Number of courses

Explanation: The weighted GPA accounts for both your grades and the credit weight of each course, while the average percentage gives equal weight to all courses.
