Calculation of cutoff for IIT JAM Mathematics Exam

The Indian Institutes of Technology (IITs) follow a specific procedure to calculate the cutoff for the IIT JAM Mathematics Exam. The cutoff is the minimum score required by a candidate to qualify for admission to the postgraduate programs offered by the IITs. Below are the steps involved in calculating the cutoff:

Step 1: Determining the total number of candidates
- The first step in calculating the cutoff is to determine the total number of candidates who appeared for the IIT JAM Mathematics Exam.
- This information is obtained from the registration data provided by the candidates.

Step 2: Normalization of scores
- In the IIT JAM Mathematics Exam, multiple sets of question papers are prepared to ensure fairness.
- After the exam, the raw scores obtained by the candidates are normalized to account for any variations in the difficulty level of different question sets.
- This helps in ensuring that the scores are comparable across different sets of question papers.

Step 3: Calculation of the All India Rank (AIR)
- Once the scores are normalized, the All India Rank (AIR) is calculated for each candidate.
- The AIR is determined based on the performance of the candidates in the exam, considering factors such as the total number of candidates, the difficulty level of the exam, and the highest score obtained.

Step 4: Determining the category-wise cutoff
- After calculating the AIR for each candidate, the category-wise cutoff is determined.
- The cutoff is the minimum score required by a candidate to qualify for admission to a specific postgraduate program.
- The cutoff varies for different categories such as General, OBC, SC, ST, etc.

Step 5: Publication of cutoff marks
- Finally, the cutoff marks are published by the IITs on their official websites.
- The cutoff marks are generally released along with the list of candidates who have qualified for admission.

It is important to note that the cutoff marks may vary each year depending on various factors such as the number of candidates, the difficulty level of the exam, and the availability of seats in the respective programs.

Overall, the calculation of the cutoff for the IIT JAM Mathematics Exam involves determining the total number of candidates, normalizing the scores, calculating the All India Rank (AIR), determining the category-wise cutoff, and publishing the cutoff marks.
