1. What is Weighted Grade Calculation?

Weighted grade calculation accounts for different weights or importance of various assignments, tests, or components in a course. It provides a more accurate representation of overall performance than a simple average.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• \( \text{grade}_i \) — Individual grade percentage
• \( \text{weight}_i \) — Weight of that grade component
• The sum is taken over all grade components

Explanation: Each grade is multiplied by its weight, these products are summed, and then divided by the total of all weights.

3. Importance of Weighted Grades

Details: Weighted grades are essential when different assignments or tests contribute unequally to the final grade. This is common in education where exams might count more than homework.

4. Using the Calculator

Tips: Enter each grade as a percentage (0-100) and its corresponding weight. Weights can be any positive numbers (they don't need to sum to 100). Click "Add Another Grade" for additional components.

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 100?
A: The calculator works with any positive weights - they will be normalized automatically. You can use percentages (e.g., 30, 70) or arbitrary numbers (e.g., 1, 3).

Q2: How many grade components can I add?
A: You can add as many as needed - there's no practical limit in the calculator.

Q3: What's the difference between weighted and unweighted average?
A: Unweighted treats all grades equally, while weighted gives more importance to grades with higher weights.

Q4: Can I use this for GPA calculation?
A: Yes, if you know the grade points and their weights, you can use this to calculate weighted GPA.

Q5: What if I have zero-weight components?
A: Components with zero weight won't affect the final grade. The calculator automatically skips them.
