1. What is Weighted Grade Calculation?

The weighted grade calculation accounts for the different importance (weights) of various assignments when calculating an overall grade. This method is commonly used in schools where different types of work (tests, homework, projects) contribute differently to the final grade.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• \( \text{grade}_i \) — Grade for assignment i (percentage)
• \( \text{weight}_i \) — Weight of assignment i (percentage)

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

3. Importance of Weighted Grades

Details: Weighted grades provide a fairer representation of student performance by giving more importance to major assessments like exams than to smaller homework assignments.

4. Using the Calculator

Tips: Enter grades as percentages (e.g., 85, 90.5) separated by commas. Enter corresponding weights (e.g., 20, 30) also separated by commas. The number of grades and weights must match.

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 100%?
A: The calculator works with any weight values as it normalizes them automatically.

Q2: Can I use decimal numbers for grades and weights?
A: Yes, the calculator accepts decimal values for both grades and weights.

Q3: What's the difference between weighted and unweighted average?
A: Unweighted average treats all assignments equally, while weighted average accounts for their different importance.

Q4: How many grades can I calculate at once?
A: You can calculate as many grades as needed, as long as you provide matching weights.

Q5: What if I get an error message?
A: Check that you have the same number of grades and weights, and that all values are valid numbers.
