How to Calculate IIT JAM Scores?

Students can easily make an estimation on JAM scores. Candidates can check this easy formula to calculate JAM marks below:

  • For one mark questions (A):

IIT JAM score = {(number of correct answers*1)-(number of incorrect answers*⅓)}

  • For two marks questions (B):

IIT JAM score = {(number of correct answers*1)-(number of incorrect answers*⅔)}

  • Finally, IIT JAM final score = (A+B)

What after the IIT JAM Response Sheet is out?

Firstly, students can take printed copies of their recorded responses after it is out. Then, print out the JAM answer key and keep them side by side. Take a blank piece of paper and evaluate your recorded responses based on the marking scheme. Finally, calculate all the positive and negative markings and you will have the final score.

Error in JAM Answer key 2025? What Next?

In case you spot any errors in the IIT JAM 2025 answer key, you can challenge the answers from February 14 to 20 in online mode. To raise objections against JAM answer key 2025 you need to pay Rs 500 per question. The JAM answer key is released after the expert committee evaluates all the objections raised against the answer key. The JAM result will be released tentatively on March 19, 2025.
