How to Calculate Weighted Grade

Calculating a weighted grade is essential for students to accurately assess their overall performance in a course. This calculation takes into account the varying importance of different components such as assignments, projects, quizzes, and exams. Here's a comprehensive guide on how to calculate your weighted grade:

Weighted Grade Formula

The formula to calculate the weighted grade is:

\[ \text{Weighted Grade} = \frac{\sum (\text{Grade} \times \text{Weight})}{\sum \text{Weight}} \]

Where:

• Grade = The score you received for each component
• Weight = The percentage of the total grade that each component is worth

Calculation Steps

1. Identify all graded components and their respective weights
2. Convert all grades to percentages if they aren't already
3. Multiply each grade by its weight
4. Sum all the weighted grades
5. Sum all the weights
6. Divide the sum of weighted grades by the sum of weights
7. Convert the result to a percentage if desired

Example Calculation

Let's calculate the weighted grade for a student with the following scores:

• Homework: 85% (Weight: 20%)
• Midterm Exam: 78% (Weight: 30%)
• Final Project: 92% (Weight: 25%)
• Final Exam: 88% (Weight: 25%)

1. Calculate weighted grades:
   • Homework: 85 × 0.20 = 17
   • Midterm Exam: 78 × 0.30 = 23.4
   • Final Project: 92 × 0.25 = 23
   • Final Exam: 88 × 0.25 = 22
2. Sum weighted grades: 17 + 23.4 + 23 + 22 = 85.4
3. Sum weights: 0.20 + 0.30 + 0.25 + 0.25 = 1.00
4. Calculate final weighted grade: 85.4 ÷ 1.00 = 85.4%

Therefore, the student's weighted grade is 85.4%.
