How the Curve Grade Calculator Works
Three powerful methods:
- Bell Curve: Z-score → letter grade based on standard deviations
- Linear: Scale all scores to match desired mean
- Custom: Add fixed points to every score
Bell Curve Grade Calculator: Standard Method
Most common in large classes:
- Mean ± 0.5σ: B range
- ±1.0σ: A and C
- ±1.5σ: A+ and C-
- ±2.0σ: A++ and D/F
Grade Curve Calculator with Mean: Linear Scaling
Formula: New Score = Old Score × (Desired Mean / Current Mean)
Preserves relative performance while adjusting difficulty.
