A Quiz Grade Calculator is a tool ro formula used to calculate the overall grade or score for quizzes or tests based on individual scores obtained in each quiz. Typically, it involves summing up the scores of all quizzes and then determining the average or total percentage score, depending on how the grade system is structured.
To use the Quiz Grade Calculator shown in the image, follow these steps:
In the 'Total Questions' input field, type the total number of questions in your quiz. For example, if your quiz has 10 questions, enter '10'.
In the 'Wrong Answers' input field, type the number of questions you answered incorrectly. For example, if you got 2 questions wrong, enter '2'.
The calculator will automatically compute your grade based on the total questions and wrong answers provided. It will display the formula and the result as a percentage. For example, if you answered all 10 questions correctly and got 0 wrong answers, it will display (10 / 10) × 100% = 100%.
The calculator will show your percentage grade and the corresponding letter grade based on the American Grading System. For instance, 100% would correspond to an 'A+'.
If you prefer to see the grade with decimal points, check the 'Show Decimals' checkbox. This will display the grade percentage with decimals if applicable.
Refer to the 'Easy Grading Chart' section to quickly see the percentage grade for different numbers of wrong answers. For example, if you have 2 wrong answers, you can see that your percentage grade would be 80%.
If you want to use a different grading system, click the 'Customize Table' button to adjust the letter grades, GPA, and percentage ranges according to your preferred grading system.
The functionality of this quiz grade calculator is straightforward. It calculates grades using the following procedure:
Grade = (X - Y) / X × 100%
Where,
X = Total no of quiz questions.
Y = No of wrong answers.
Let’s consider an example to illustrate how the quiz grade calculator works:
Total number of quiz questions (X): 20
Number of wrong answers (Y): 3
Therefore, the number of correct answers:
Correct Answers = X - Y = 20 - 3 = 17
Now, the percentage grade:
Grade = (X - Y) / X × 100% = (17 / 20) × 100% = 85%
You can determine the corresponding letter grade of the calculated percentage grade.
