1. What is Weighted Grade?

A weighted grade is a calculation that takes into account the varying degrees of importance (weights) of different assignments, tests, or components in a course. It provides a more accurate representation of a student's overall performance.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• \( \text{grade}_i \) — The grade received for assignment/test \( i \) (in percentage)
• \( \text{weight}_i \) — The weight of assignment/test \( i \) (in percentage of total grade)

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

3. Importance of Weighted Grades

Details: Weighted grades help students understand how different assignments affect their final grade. They are commonly used in education to emphasize the importance of certain assignments (like finals or major projects) over others.

4. Using the Calculator

Tips: Enter each grade and its corresponding weight. You can add multiple grade/weight pairs. All grades should be between 0-100%, and weights should reflect their percentage of the total grade.

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 100%?
A: The calculator will still work - it calculates the weighted average based on the relative weights you provide.

Q2: Can I use this for different grading systems?
A: Yes, as long as you can express both grades and weights numerically (e.g., 90% or 0.9 for an A-).

Q3: How many grade/weight pairs can I enter?
A: You can add as many as needed - the calculator will handle all of them.

Q4: What's the difference between weighted and unweighted average?
A: Unweighted average treats all grades equally, while weighted average accounts for their different importance.

Q5: Can I use decimals for grades and weights?
A: Yes, the calculator accepts decimal values for more precise calculations.
