1. What is Weighted Grade?

A weighted grade is calculated by multiplying each grade by its weight, summing these products, and then dividing by the sum of all weights. This gives more importance to assignments with higher weights in the final grade calculation.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• Grade — Individual assignment/test grade (percentage)
• Weight — Importance of that assignment (percentage)
• Σ — Sum of all values

Explanation: The equation accounts for different assignment weights in calculating an overall course grade.

3. Importance of Weighted Grades

Details: Weighted grades provide a more accurate representation of student performance when different assignments contribute unequally to the final grade.

4. Using the Calculator

Tips: Enter grades and corresponding weights as percentages. You can separate values by commas or new lines. Both lists must have the same number of items.

5. Frequently Asked Questions (FAQ)

Q1: How do I enter my grades?
A: Enter your grades as percentages (e.g., 85, 90, 78) separated by commas or on separate lines.

Q2: What if my weights don't add up to 100%?
A: The calculator works with any weights - they don't need to sum to 100% as the formula normalizes them.

Q3: Can I use this for different grading systems?
A: Yes, as long as all grades use the same scale (e.g., all percentages or all 4.0 scale).

Q4: What if I have letter grades?
A: Convert letter grades to their numerical equivalents before entering them.

Q5: How accurate is this calculator?
A: It provides mathematically precise weighted averages based on your input.
