- A. Australian Grading System
- B. American Grading System
- C. British Grading System
- D. Canadian Grading System
- E. Indian Grading System
- F. Chinese Grading System
- G. Russian Grading System
You can choose between any of the following two methods based on your requirements:
- a. Using the difference between maximum possible grade and highest earned grade.
- b. Using the ratio between maximum possible grade and highest earned grade.
Enter the following parameters:
- Maximum possible grade (%)
- Highest earned grade (%)
- Student's original grade (%)
The calculator will automatically adjust your grades according to the curve.
You can click on the 'Reset' button to enter new values.

Now, read the following section to get an understanding of how this calculator works. It describes each method and calculates it using some real-world data.

How to Calculate Curved Grade?

Grade curving is a method used to adjust student scores to fit a desired distribution, often making grades more reflective of performance relative to peers. Here are two simple methods to calculate curved grade:

1. Using the Difference Between Maximum Possible Grade and Highest Earned Grade

To calculate the grade curve using the differences between the maximum possible grade and the highest earned grade, follow the below formula:

Curved Grade = Go + (Gm - Gh)

Here,

Gm = Maximum possible grade (%)
Gh = Highest earned grade (%)
Go = Student's original grade (%)

Example Calculation:
Imagine Sarah, a high school student. The maximum possible grade is 100%, the highest earned grade is 80%, and Sarah's original grade is 75%.

Curved Grade = 75 + (100 - 80) = 75 + 20 = 95

Sarah’s curved grade would be 95%.

2. Using the Ratio Between Maximum Possible Grade and Highest Earned Grade

To calculate the grade curve using the ratio between the maximum possible grade and the highest earned grade, follow the below formula:

Curved Grade = Go × ^Gm⁄_Gh

Here,

Gm = Maximum possible grade (%)
Gh = Highest earned grade (%)
Go = Student's original grade (%)

Example Calculation:
Now consider Mike, another student. The maximum possible grade is 100%, the highest earned grade is 95%, and Mike's original grade is 75%.

Curved Grade = 75 × ¹⁰⁰⁄₉₅ = 75 × 1.053 = 78.947

Mike’s curved grade would be approximately 78.947%.

Benefits of a Simple Grade Curve

Fair Assessment: Adjusts for variations in exam difficulty and teaching methods.
Student Motivation: Encourages students by potentially improving their grades.
Equity: Ensures grades reflect relative performance within the class.

Frequently Asked Questions (FAQs)

How much can a curve affect your grade?

A curve can significantly affect your grade by adjusting the distribution of scores. If a class performs poorly on an exam, a curve might raise everyone’s grades to better fit a predetermined distribution, such as a bell curve. This can improve individual grades, potentially raising them by a full letter grade or more, depending on the severity of the curve.

Is curving grades ethical?

The ethics of curving grades can be debated. Some argue it is fair as it accounts for varying difficulty levels of exams and maintains grade distribution. Others believe it can be unfair, especially if it pits students against each other, or if it reduces the incentive to improve understanding and performance independently.

What is the curve method of grading?

The curve method of grading adjusts student scores based on the overall performance of the class. This can involve setting the highest score as the new benchmark or distributing grades along a bell curve. It aims to normalize scores and account for exam difficulty or varying levels of student ability.

What are the cons of curving grades?

The cons of curving grades include creating competition among students, potentially lowering morale, and unfairly inflating or deflating grades. It may also reduce motivation for students to strive for mastery, as they might rely on the curve rather than their understanding and effort.

Does curving grade help students?

Curving grades can help students by mitigating the impact of a particularly difficult exam or by adjusting for inconsistencies in grading. It can raise lower scores, helping students achieve better overall grades. However, its effectiveness depends on its implementation and the specific academic context.

Are professors allowed to curve downgrades?

Professors generally have the discretion to curve grades, but curving down (lowering grades) is less common and can be controversial. Institutions typically have policies regarding grading practices, and curving down might be considered unfair or demotivating. Professors are encouraged to be transparent about their grading policies from the start.
