How to Use the Grade Curve Calculator
Enter your original score and total possible points, then select a curve method. The calculator will show your adjusted score, percentage, and estimated letter grade.
Example
Suppose you scored 72 out of 100 on an exam, and your teacher adds 5 points to everyone’s score.
- Original score: 72/100
- Curve adjustment: +5 points
- Adjusted score: 77/100
- Final percentage: 77%
Your adjusted grade would be 77%. Actual grading rules depend on your teacher or school.
