Curve Grade Calculator Formula
Understand the math behind the curve grade calculator. Each variable explained with a worked example.
Formulas Used
Flat Curve Result
flat_result = flat_curved > 100 ? 100 : flat_curvedSquare Root Curve Result
sqrt_result = sqrt_curvedHighest=100 Curve Result
highest_result = highest_curvedVariables
| Variable | Description | Default |
|---|---|---|
raw_score | Your Raw Score(%) | 68 |
curve_points | Points to Add (Flat Curve) | 10 |
highest_score | Highest Score in Class(%) | 92 |
flat_curved | Derived value= raw_score + curve_points | calculated |
sqrt_curved | Derived value= sqrt(raw_score / 100) * 100 | calculated |
highest_curved | Derived value= raw_score + (100 - highest_score) | calculated |
How It Works
How Grade Curves Work
Flat Curve
Add a fixed number of points: Curved = Raw + PointsSquare Root Curve
Curved = sqrt(Raw / 100) x 100 Benefits lower scores more than higher scores.Highest Score = 100
Curved = Raw + (100 - Highest Score) Everyone gets the same boost.Worked Example
Raw score of 68%, flat curve of 10, class high of 92%.
raw_score = 68curve_points = 10highest_score = 92
- 01Flat curve: 68 + 10 = 78%
- 02Square root: sqrt(0.68) x 100 = 82.5%
- 03Highest=100: 68 + (100 - 92) = 76%
