Hi Candidate,
JEE MAINS is held twice in a year from the year 2019 and is conducted by the Nation Testing Agency (NTA). The better of the two attempts is taken into consideration for the Final Result and Score Card.
Category certificate plays an important role in determining the seat which the candidate gets, since there is special reservation criteria for different categories in government colleges. If a candidate fails to submit the correct and updated Category Certification during the Document Verification, then his/her Alloted seat might get cancelled and he has to apply for the General Category itself irrespective of the category.
Hope that this answer helps you. All The Best!!
