Every student asks themselves: how exactly is the grade average calculated? The answer depends on the school and grading system. Most schools use weighted averages.
Simple Grade Average
The simplest way to calculate an average is to add all grades and divide by their count. This method treats all grades equally - a quiz has the same value as a major test.
Example: You have grades 5, 4, 3, 5. Sum: 17. Number of grades: 4. Average: 17 / 4 = 4.25
Weighted Grade Average
Most schools use weighted averages, where grades have different weights. A test with weight 3 counts three times more than an oral response with weight 1. This way, more important assessments have a greater impact on the average.
Example: Test (weight 3): 4, Quiz (weight 1): 5. Calculation: (4×3 + 5×1) / (3+1) = 17/4 = 4.25
How Do Different Systems Calculate Averages?
Different schools and countries use different grading systems. Our calculator supports all these systems and will help you accurately calculate your average.
How to Improve Your Grade Average?
To quickly improve your average, focus on grades with high weight - tests and major assignments. One good grade on a test (weight 3) can balance out several poor quiz grades (weight 1). Regularly check your average and use our calculator for simulations.
