Test Score Calculator

Step-by-Step Guide to Using the Test Score Calculator

Introduction

The Test Score Calculator is a practical tool designed for calculating the percentage score of a test based on the number of correct answers. It also computes the number of incorrect answers and assigns a letter grade depending on the final percentage score. Here’s how you can use it effectively.

Step 1: Input the Total Number of Questions

• Field: Total Number of Questions
• Type: Number
• Instructions: Enter the complete total number of questions on the test. This number must be between 1 and 1000.
• Example: If a test consists of 50 questions, you should enter “50”.

Step 2: Enter the Number of Correct Answers

• Field: Number of Correct Answers
• Type: Number
• Instructions: Input the number of questions you answered correctly.
• Validation: It must be a number equal to or greater than 0.
• Example: If you answered 40 questions correctly, input “40”.

Step 3: Select the Test Weightage

• Field: Test Weightage
• Type: Select (Dropdown Menu)
• Instructions: Choose the appropriate weightage for the test from the following options:
• Regular (100%) – Select this if the test holds the standard full weightage.
• Half Weight (50%) – Choose this for tests assessed for half their regular significance.
• Extra Weight (150%) – Use this for tests that are of extra importance.
• Example: If the test has a regular weight, select “Regular (100%)”.

Step 4: Review Your Results

Once all required fields are filled, the calculator will process your inputs to provide the following results:

• Percentage Score: This reflects your performance in percentage terms, calculated using the formula: (correctAnswers / totalQuestions) * 100 * weightage. The score is rounded to two decimal places and displayed with a ‘%’ sign.
• Incorrect Answers: This shows how many questions you got wrong, determined by subtracting the number of correct answers from the total questions. It is displayed as a whole number.
• Letter Grade: The score is then translated into a letter grade based on standard grading systems:
• A: 90% and above
• B: 80% to 89%
• C: 70% to 79%
• D: 60% to 69%
• F: Below 60%

Conclusion

The Test Score Calculator is a straightforward tool to assess test performances quickly. By following these steps, users can efficiently determine their test score percentage, identify the number of incorrect answers, and obtain the corresponding letter grade.
