1. What is Weighted Grade?

A weighted grade is a calculation that takes into account the varying degrees of importance of different components in a course. It gives more weight to some assignments/exams than others based on their significance in the overall course.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• Grade — The percentage score for each component
• Weight — The relative importance of each component (as a decimal between 0 and 1)
• Σ — Sum of all components

Explanation: Each grade is multiplied by its weight, these products are summed, and then divided by the sum of all weights to get the overall weighted grade.

3. Importance of Weighted Grades

Details: Weighted grades provide a more accurate representation of student performance when different assignments have different levels of importance. They help students understand where to focus their efforts.

4. Using the Calculator

Tips:

• Enter each grade as a percentage (0-100)
• Enter weights as decimals (e.g., 0.25 for 25%)
• The sum of weights doesn't need to equal 1 - the calculator normalizes them
• Add as many grade items as needed

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 1 (100%)?
A: The calculator automatically normalizes the weights, so they don't need to add up to 1. It will calculate the correct weighted average regardless.

Q2: How is this different from a regular average?
A: A regular average treats all components equally, while a weighted average gives more importance to components with higher weights.

Q3: Can I use this for semester grades?
A: Yes, this is perfect for calculating semester grades where exams, homework, and projects have different weights.

Q4: What's the maximum number of grade items I can add?
A: You can add as many as you need - the calculator will handle all of them.

Q5: Can I use fractions for weights?
A: Yes, you can enter weights as fractions (e.g., 0.333 for 1/3) or percentages (e.g., 0.25 for 25%).
