How to Use the Grade Calculator – Complete Guide

What is the Grade Calculator?

The Grade Calculator helps you determine your overall course grade based on your scores in different assignments, tests, quizzes, and projects. It offers three calculation methods to suit different grading systems.

Getting Started

Step 1: Select Calculator Type Choose one of three options:

1. Simple Grade Calculator – Averages 3 components equally
2. Weighted Grade Calculator – Assigns different weights to each component
3. Multi-Assignment Calculator – Calculates average from multiple assignments

Using Simple Grade Calculator

This calculator is for courses where all components count equally.

Steps:

1. Select “📄 Simple Grade Calculator”
2. Enter your Assignments Score (0-100)
3. Enter your Tests Score (0-100)
4. Enter your Quizzes Score (0-100)
5. Click “Calculate Grade”

Result: Shows your overall percentage and letter grade (A, B, C, D, F)

Example:

• Assignments: 85%
• Tests: 92%
• Quizzes: 88%
• Result: (85+92+88)÷3 = 88.33% = B

Using Weighted Grade Calculator

This calculator is for courses where different components have different importance. Your teacher might say “Tests are worth 40%, Assignments 20%, Quizzes 20%, Projects 20%.”

Steps:

1. Select “⚖️ Weighted Grade Calculator”
2. Enter each component’s Score (0-100)
3. Enter each component’s Weight (%)
4. IMPORTANT: Total weights MUST equal 100%
5. Click “Calculate Grade”

Example:

• Assignments: 85% (weight 20%) = 17 points
• Tests: 90% (weight 40%) = 36 points
• Quizzes: 88% (weight 20%) = 17.6 points
• Projects: 95% (weight 20%) = 19 points
• Result: 89.6% = B

Tip: If total weight doesn’t equal 100%, the calculator will show an error.

Using Multi-Assignment Calculator

Perfect when you have many assignments with different point values.

Steps:

1. Select “📋 Multi-Assignment Calculator”
2. Enter how many assignments you have
3. Click “Generate Assignment Fields”
4. For each assignment, enter:
   • Your score (actual points earned)
   • Maximum score (total points possible)
5. Click “Calculate Grade”

Example:

• Assignment 1: 18/20 = 90%
• Assignment 2: 42/50 = 84%
• Assignment 3: 9/10 = 90%
• Average: (90+84+90)÷3 = 88% = B
