What is an OMR Sheet Answer Calculator?

An OMR (Optical Mark Recognition) Sheet Answer Calculator is a digital tool designed to simulate and evaluate OMR-based tests, commonly used in multiple-choice examinations. The tool allows users to:

• Input correct answers (answer key) for a set of questions.
• Mark responses on a virtual OMR sheet (e.g., selecting A, B, C, or D for each question).
• Calculate results based on predefined parameters such as marks per question, negative marking, and total questions.
• Display metrics like total marks, percentage, correct answers, and wrong answers.
• Export results (e.g., as a PDF).

The specific implementation provided includes features like a responsive design, dynamic question generation, marks and negative marking dropdowns, reset functionality, and PDF download, making it suitable for educational and testing purposes.

How to Use the OMR Sheet Answer Calculator?

Using the OMR Sheet Answer Calculator (based on the provided code) involves the following steps:

1. Access the Tool:
   • Embed the HTML, CSS, and JavaScript code in a WordPress post or a standalone webpage.
   • Ensure the files (index.html, styles.css, script.js) are correctly linked, and the jsPDF library is included for PDF functionality.
2. Configure Settings:
   • Total Questions: Enter the number of questions in the input field (e.g., 10). The OMR sheet and answer key will dynamically adjust to this number.
   • Marks per Question: Select the marks awarded for each correct answer (1, 2, 3, or 4) from the dropdown.
   • Negative Marking: Choose a negative marking value (None, 0.25, 0.5, or 1) for incorrect answers from the dropdown.
3. Set the Answer Key:
   • In the “Answer Key” section, for each question, select the correct answer (A, B, C, or D) from the dropdown menu.
4. Fill the OMR Sheet:
   • In the “OMR Sheet” section, click on the circular option (A, B, C, or D) for each question to mark your answer. Only one option can be selected per question, and clicking another option will deselect the previous one.
5. Calculate Results:
   • Click the “Calculate Results” button to compute:
     • Total Marks: (Correct Answers × Marks per Question) – (Wrong Answers × Negative Marking).
     • Percentage: (Total Marks / Maximum Possible Marks) × 100.
     • Correct Answers: Number of answers matching the answer key.
     • Wrong Answers: Number of incorrect answers marked.
   • Results are displayed in the “Results” section.
6. Reset the Sheet:
   • Click the “Reset” button to clear all inputs and selections, reverting to default values (10 questions, 1 mark per question, no negative marking).
7. Download Results:
   • Click the “Download Result as PDF” button to generate and download a PDF file containing the result summary (total questions, marks per question, negative marking, total marks, percentage, correct and wrong answers).
