Curve Grading Calculator
The Curve Grading Calculator adjusts student grades based on established grading curves. It helps normalize scores, ensuring fair evaluation in difficult exams or competitive courses.
How It Works
Grades are adjusted to fit a predetermined distribution. Common methods include:
- Linear Adjustment: Add a fixed number of points to each student’s score.
Adjusted Score = Raw Score + Curve Adjustment - Scaling to Highest Score: The top score is scaled to 100, and others proportionally.
Adjusted Score = (Raw Score / Highest Score) × 100 - Standard Deviation (Bell Curve): Grades are distributed according to the class mean and standard deviation.
- Percentile Ranking: Students are assigned grades based on performance percentiles.

Example Calculations
Scenario 1: Linear Adjustment
Raw Scores: 65, 70, 85, 90; Curve Adjustment: +10
Adjusted Scores = 75, 80, 95, 100
Scenario 2: Scaling to Highest Score
Raw Scores: 60, 75, 90; Highest Score = 90
Adjusted Scores = (60/90)×100 = 66.67
(75/90)×100 = 83.33
(90/90)×100 = 100
