Formula Explanation
Assignment Grade % = (Points Earned ÷ Total Points) × 100
Example:
38 earned ÷ 45 total × 100 = 84.4% → B
17 earned ÷ 20 total × 100 = 85% → B
195 earned ÷ 200 total × 100 = 97.5% → A+
Example Calculation
Essay Assignment:
Points Earned: 43
Total Points: 50
Percentage: (43 ÷ 50) × 100 = 86% → B
Lab Report:
Points Earned: 27
Total Points: 30
Percentage: (27 ÷ 30) × 100 = 90% → A-
Research Project:
Points Earned: 112
Total Points: 130
Percentage: (112 ÷ 130) × 100 = 86.2% → B

Frequently Asked Questions (FAQ)
Q: How do I calculate my grade on an assignment?
