1. What is Weighted Average Grade?

The weighted average grade (wavg) is a calculation that takes into account the varying importance (weights) of different grades. It's commonly used in academic settings where courses have different credit values.

2. How Does the Calculator Work?

The calculator uses the weighted average formula:

Where:

• \( grade_i \) — Grade for course i (percentage)
• \( credit_i \) — Credit value for course i
• \( \sum \) — Summation of all courses

Explanation: Each grade is multiplied by its corresponding credit value, these products are summed, and then divided by the total number of credits.

3. Importance of Weighted Average

Details: Weighted averages provide a more accurate representation of overall performance than simple averages, especially when courses have different workloads or importance.

4. Using the Calculator

Tips: Enter grades as percentages separated by commas, and corresponding credit values in the same order. Both fields must contain the same number of values.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between weighted and unweighted average?
A: Unweighted average treats all grades equally, while weighted average accounts for different credit values.

Q2: How should I format the input?
A: Enter numbers separated by commas (e.g., "85, 90, 78" for grades and "3, 4, 2" for credits).

Q3: Can I use decimal grades or credits?
A: Yes, the calculator accepts decimal values for both grades and credits.

Q4: What if my grades and credits lists are different lengths?
A: The calculator will only process pairs of grades and credits, extra values will be ignored.

Q5: How is this different from GPA calculation?
A: GPA typically uses letter grades converted to points on a fixed scale (e.g., 4.0), while this calculates directly from percentage grades.
