How to Calculate Weighted Grade?

To calculate a weighted grade, you need to assign different weights or percentages to each assignment. Such as projects, midterms, homework, and quizzes, and then multiply the grade earned in each assignment by its corresponding weight. Finally, add up these weighted grades and divide them by the sum of weights to obtain an overall weighted grade.

Weighted grade =  
w1×g1 + w2×g2 + w3×g3 + ...
w1 + w2 + w3 + ...

Here's an example:

Suppose there are three categories of assignments:

  • Projects (weight of 35%)
  • Midterms (weight of 40%)
  • Homework (weight of 25%)

A student earns the following grades in each category:

  • Projects - 75%
  • Midterms - 90%
  • Homework - 82%

Weighted grade = (project grade × 35%) + (midterm grade × 40%) + (homework grade × 25%) / 35 + 40 + 25

= (75 × 35) + (90 × 40) + (82 × 25) / 100

= (2625 + 3600 + 2050) / 100

= 8275 / 100

= 82.75%

Therefore, the student's overall weighted grade for the course is 82.75%.
