 Welcome to our online grading calculator! This user-friendly tool allows you to calculate your grade on an assignment, test, quiz, and more, based on the number of problems and the number of wrong answers.

Number of Questions:

Number wrong:

## Instructions

1. In the first input field, enter the total number of problems. You can quickly adjust this number by using the plus/minus buttons.
2. In the second input field, enter the number of questions that are wrong. This value can also be adjusted by using the plus/minus buttons.

Once both fields have been filled in, the grade will be automatically calculated.

To calculate your grade, you will need to know the total number of questions and the number of answers that you got wrong. Once you have that information, you subtract the number you got wrong from the total number of questions. Then you divide by the total number of questions. Finally, multiple by 100 to find your grade as a percentage.

grade percentage = ((total number of questions - number wrong) / total number of questions) x 100

## Example Calculation

Here's an example of how you would use the formula to calculate your grade:

Let's say you took a test with 50 questions and got 5 of them wrong.

To calculate your grade, you would plug the numbers into the formula: (50 - 5) / 50 x 100 = 90
