Dear Rehan,

Yes there is a possibility. If you are in the top 20 percentile in the 12th class examination conducted by the respective Boards,then you are also eligible for it.

As stated by the NTA

"JEE Main is applicable for admission to NITs, IIITs and CFTIs participating though Central Seat Allocation Board subject to the condition that the candidate should have secured at least 75% marks in the 12th class examination, or be in the top 20 percentile in the 12th class examination conducted by the respective Boards. For SC/ST candidates the qualifying marks would be 65% in the 12th class examination."

To know about that you come under to 20 percentile, you should contact your respective board.
