1. What is a Grade Calculator?

Definition: This calculator determines the percentage grade based on points earned versus total possible points.

Purpose: It helps students and educators quickly calculate grades for assignments, tests, or overall course performance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — Grade percentage
• \( R \) — Points earned
• \( T \) — Total possible points

Explanation: The points earned are divided by total points to get a decimal value, then multiplied by 100 to convert to percentage.

3. Importance of Grade Calculation

Details: Accurate grade calculation helps track academic progress, identify areas needing improvement, and maintain fair evaluation standards.

4. Using the Calculator

Tips: Enter the points you earned and the total possible points. Both values must be positive numbers, and earned points cannot exceed total points.

5. Frequently Asked Questions (FAQ)

Q1: Can I use decimals for points?
A: Yes, you can enter decimal values for partial points (e.g., 87.5 out of 100).

Q2: What if I enter more earned points than total points?
A: The calculator won't compute invalid inputs where earned points exceed total points.

Q3: How do I convert percentage to letter grade?
A: Common scales: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%).

Q4: Can I calculate weighted grades with this?
A: No, this calculates simple percentages. For weighted grades, you'd need to calculate each component separately.

Q5: How precise are the results?
A: Results are shown to two decimal places for accuracy.
