1. What is a Grade Calculator Using Weights?

Definition: This calculator computes a weighted average grade based on individual grades and their respective weights.

Purpose: It helps students and educators determine final grades when different assignments or exams carry different weights.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Grade — The final weighted grade (%)
• Grade_n — Individual grade components (%)
• Weight_n — Relative weight of each component
• Total Weight — Sum of all weights

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

3. Importance of Weighted Grade Calculation

Details: Weighted grades provide a fair assessment when different course components (exams, homework, projects) have different importance.

4. Using the Calculator

Tips: Enter up to 3 grade/weight pairs. Grades should be percentages (0-100), weights can be any positive numbers (higher = more important).

5. Frequently Asked Questions (FAQ)

Q1: What if I have more than 3 components?
A: Combine similar components or calculate in stages (e.g., first calculate category averages, then the final grade).

Q2: Do weights need to add up to 100?
A: No, the calculator normalizes the weights automatically. You can use any positive numbers.

Q3: Can I leave some fields blank?
A: Yes, only fill in the grade/weight pairs you need. At least one complete pair is required.

Q4: How are decimals handled?
A: Grades and weights can have up to 2 decimal places for precision.

Q5: What if I get an unexpected result?
A: Double-check that all entered grades are between 0-100 and weights are positive numbers.
