1. What is Weighted Grade Calculation?

The weighted grade calculation determines your overall grade when different components of your course have different weights or percentages. It provides a more accurate reflection of your performance than a simple average.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• \( WG \) — Weighted Grade
• \( p_i \) — Percentage weight of component i
• \( g_i \) — Grade received in component i

Explanation: Each grade is multiplied by its weight percentage, summed together, then divided by the total weight.

3. Importance of Weighted Grades

Details: Weighted grades are crucial for accurately calculating final grades in courses where different components (exams, homework, projects) contribute differently to the final grade.

4. Using the Calculator

Tips: Enter each grade (0-100%) and its corresponding weight percentage (0-100%). The sum of weights doesn't need to equal 100 as the calculator normalizes the result.

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 100%?
A: The calculator automatically normalizes the weights, so they don't need to add up to exactly 100%.

Q2: Can I add more than three components?
A: This calculator handles three components. For more components, you would need to extend the formula.

Q3: How are letter grades calculated?
A: First calculate the weighted percentage, then apply your institution's grading scale to determine the letter grade.

Q4: What if I have extra credit?
A: Add the extra credit as an additional component with its grade and weight.

Q5: How accurate is this calculator?
A: It provides mathematically precise calculations based on the inputs you provide.
