An average grade is a numerical representation of a student's overall academic performance. It is computed by summing individual grades and dividing the total by the number of grades. The resulting figure provides an intuitive measure of academic achievement over a specific period or across various subjects.
Calculating the average grade is a fundamental step for both students and educators to assess academic performance over a period of time. Whether you're a student trying to keep track of your grades or a teacher compiling grades for report cards, understanding how to calculate the average grade is essential. In this comprehensive guide, we will explain the steps involved in calculating average grades and provide examples to illustrate the process.
Below are the steps to calculate weighted average grade:
1. Determine Grade and Weight: Determine your grade on each assignment and the weight of the grade.
2. Multiply Grade by Weight: Multiply the grade on the assignment by the grade weight.
3. Add together.
Weighted grade = w1×g1+ w2×g2+ w3×g3+...
Example:
Language course with grade of 85 and weight of 35%.
Science course with grade of 80 and weight of 40%.
History course with grade of 75 and weight of 25%.
The weighted average grade is calculated as:
 = 35%×85 + 40%×80 + 25%×75 = 80.5
When the weights of modules are not in percentage, an additional step is required: divide the weighted sum by the sum of the weights:
Example:
Language grade is 80, earned 3 credits.
Science grade is 90, earned 5 credits
History grade is 75, earned 2 credits
Weighted average grade is calculated as:
