1. What is a Weighted Grade Calculator?

Definition: This calculator computes your overall grade when different assignments/exams carry different weights.

Purpose: Helps students understand how individual grades contribute to their final course grade based on weighting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — Weighted grade (%)
• \( g_i \) — Individual grade (%)
• \( w_i \) — Weight of each grade

Explanation: Each grade is multiplied by its weight, summed together, then divided by the total weights.

3. Importance of Weighted Grades

Details: Many courses weight different components (exams, homework, projects) differently. Understanding this helps prioritize study efforts.

4. Using the Calculator

Tips: Enter up to 3 grades with their respective weights. Weights can be percentages or point values (the calculator normalizes them).

5. Frequently Asked Questions (FAQ)

Q1: What if my course has more than 3 components?
A: You can combine similar components or calculate in stages (e.g., first calculate homework average, then use that as one input).

Q2: How do I know the weights for my course?
A: Check your syllabus or ask your instructor. Common weights: Exams 50%, Homework 20%, Projects 30%.

Q3: Should weights add up to 100%?
A: Not necessarily - the calculator normalizes them. You could enter 1, 2, 2 or 25%, 50%, 50% - both would give the same result.

Q4: Can I calculate what I need on the final?
A: Leave one grade blank and adjust it until you reach your desired course grade.

Q5: Does this work for GPA calculation?
A: No, this is for course grades. GPA calculation uses a different scale (typically 4.0 scale).
