IIT JAM Chemistry Exam - Calculation of Final Score using Answer Key and Marking Scheme

Introduction
The IIT JAM (Joint Admission Test for M.Sc.) is a national-level entrance exam conducted by the Indian Institutes of Technology (IITs) for admission to various postgraduate programs in Science. The Chemistry paper of IIT JAM consists of multiple-choice questions (MCQs) with negative marking for incorrect answers.

Method to Calculate Final Score

Step 1: Obtain the Answer Key
The first step is to obtain the official IIT JAM Chemistry answer key, which is usually released by the organizing institute after a few days of the exam. The answer key contains the correct answers to all the questions asked in the exam.

Step 2: Evaluate the Answers
Once you have the answer key, compare it with your own recorded answers. For each question, mark it as correct or incorrect based on the answer key.

Step 3: Marking Scheme
The marking scheme for IIT JAM Chemistry is as follows:
- For each correct answer, you will be awarded +1 mark.
- For each incorrect answer, -1/3 (negative one-third) mark will be deducted.
- There is no negative marking for unanswered questions or questions marked for review.

Step 4: Calculate Total Score
To calculate your total score, add up the total number of correct answers and multiply it by 1. Then, subtract the total number of incorrect answers multiplied by 1/3.

Step 5: Final Score
The final score is the net score obtained after deducting the negative marks from the total positive marks. The formula to calculate the final score is as follows:
Final Score = (Total Correct Answers * 1) - (Total Incorrect Answers * 1/3)
