Calculating Approximate Score based on Marking Scheme in IIT JAM Physics Exam

To calculate your approximate score in the IIT JAM Physics exam, you need to understand the marking scheme of the exam and follow a systematic approach. Here is a step-by-step guide to help you calculate your approximate score:

Step 1: Understand the Marking Scheme
- The IIT JAM Physics exam consists of multiple-choice questions (MCQ), multiple-select questions (MSQ), and numerical answer type (NAT) questions.
- For MCQ and MSQ questions, there are negative markings. For every incorrect answer, one-third of the total marks allotted to the question are deducted.
- For NAT questions, there are no negative markings. The answer must be entered in numerical value using the virtual keyboard.

Step 2: Calculate Total Marks
- Determine the total number of questions in each section of the exam. The exam usually consists of three sections: Section A, Section B, and Section C.
- Assign the corresponding marks for each question type. For example, MCQ questions might carry one or two marks, MSQ questions might carry one or two marks, and NAT questions might carry one or two marks.
- Multiply the number of questions in each section with their respective marks to calculate the total marks for each section.

Step 3: Calculate Approximate Score
- For MCQ and MSQ questions, start by calculating the number of correct answers.
- For each correct answer, add the allotted marks to your score.
- For each incorrect answer, deduct one-third of the total marks allotted to the question from your score.
- For NAT questions, calculate the number of correct answers.
- Add the marks allotted for each correct answer to your score.

Step 4: Final Calculation
- Add the scores obtained from each section to get the final approximate score.

By following these steps, you can calculate your approximate score based on the marking scheme in the IIT JAM Physics exam. Remember, this is just an approximation, and the actual score may vary. It is always advisable to refer to the official answer key and consult with subject matter experts for a more accurate assessment of your performance.
