Hello.

The Jee mains result will be released by NTA on January 31. The answer key is for the reference of students to check their performance in the exam. However, the students can challenge an answer which is provided in the answer key which they feel is wrong by paying an amount of Rs. 1000 per question.

Hope this helps.

Hey Rushikesh

Challenging answer means if you have any doubt in the answer key for a particular or more questions than you can challenge that answer and give a justified solution and they will check and examine and if possible than it will be corrected in anawea key and your final result will be declared on 31 St of January after all corrections.

And the other link " Question paper and answer key 1 " is that question paper you attempted and the answer key of that paper.

Good luck.
