1. What is a Weighted Grade Calculator?

Definition: This calculator computes an overall grade based on multiple component grades and their respective weights.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Grade — Individual component grade (percentage)
• Weight — Relative importance of each component (unitless)
• ∑ — Sum of all components

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

3. Importance of Weighted Grades

Details: Weighted grades accurately reflect performance when different assignments contribute differently to the final grade.

4. Using the Calculator

Tips:

• Add all your graded components (exams, assignments, etc.)
• Enter each grade as a percentage (0-100)
• Enter weights according to their importance (higher numbers = more weight)
• You can add or remove grade entries as needed

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 100?
A: The calculator normalizes the weights automatically. What matters is their relative proportions.

Q2: Can I use this for non-percentage grades?
A: Yes, as long as all grades use the same scale (e.g., all out of 100 or all out of 10).

Q3: How do I determine weights?
A: Weights are typically determined by the course syllabus (e.g., midterm=30%, homework=20%, etc.).

Q4: What if I have extra credit?
A: Add the extra credit as a separate grade entry with its point value and appropriate weight.

Q5: Can I save my calculations?
A: Currently this calculator doesn't save data. You may want to note down your inputs and results.
