1. What is a Weighted Grade Calculator?

Definition: This calculator computes the weighted average of grades based on their respective weights.

Purpose: It helps students determine their overall grade when different assignments or tests carry different weights in the final grade.

2. How Does the Calculator Work?

The calculator uses the weighted average formula:

\[ \text{Grade %} = \frac{\sum(\text{Grade} \times \text{Weight})}{\sum \text{Weights}} \]

Where:

Grade — The percentage score for each component
Weight — The relative importance of each component
Σ — Sum of all components

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 accurately reflect performance when some assignments count more than others, such as finals being worth more than quizzes.

4. Using the Calculator

Tips: Enter up to 3 grade/weight pairs. Weights can be any positive numbers (they don't need to sum to 100). Grades must be between 0-100%.

5. Frequently Asked Questions (FAQ)

Q1: What if I have more than 3 components?
A: Calculate groups of 3 at a time, using the result as one component in the next calculation.

Q2: Do weights need to add up to 100?
A: No, the calculator normalizes the weights automatically.

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

Q4: Can I use this for GPA calculation?
A: Yes, if you know the grade percentages and their weights.

Q5: How do I handle extra credit?
A: Add it as an additional component with its grade and weight.
