1. What is a Weighted Grade Calculator?

Definition: This calculator computes the overall grade percentage when different components have different weights.

Purpose: It helps students and educators determine final grades based on weighted assignments, tests, and other course components.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \(\text{Grade}_i\) — Individual grade percentage for each component
• \(\text{Weight}_i\) — Weight of each component (doesn't need to be percentage)
• \(\sum\) — Summation of all components

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

3. Importance of Weighted Grades

Details: Weighted grades accurately reflect course performance when different assignments contribute differently to the final grade.

4. Using the Calculator

Tips:

• Enter grades as percentages (e.g., 85, 90, 78)
• Enter corresponding weights (e.g., 20, 30, 50)
• Number of grades must match number of weights
• Weights don't need to sum to 100 (calculator normalizes them)

5. Frequently Asked Questions (FAQ)

Q1: Do weights need to add up to 100?
A: No, the calculator automatically normalizes the weights. You can use any numbers (e.g., 1, 2, 3 or 20, 30, 50).

Q2: How many grade/weight pairs can I enter?
A: You can enter as many as needed, just separate them with commas in both fields.

Q3: What if I have different grading scales?
A: Convert all grades to percentages first before entering them into the calculator.

Q4: Can I use this for non-academic purposes?
A: Yes, it works for any situation where you need to calculate a weighted average.

Q5: How precise are the results?
A: Results are calculated to 2 decimal places for accuracy.
