Hello Aspirant,

  Board percentage criteria is already removed by officials. Now board percentage is not consiered for final rank calculation, so only Jee Mains marks are used for Jee Mains final rank and same is the case with Jee Advance. But for admission in IITs you have to be in top 20 percentile in respective category in board examination. Jee releases top 20 percentile for every board, wait for some time and you will get the list. Now if you are not in top 20 percentile then you can fill the form of improvement and if you get in top 20 percentile (or more than 75%) then you will be eligible for Jee.

 Good Luck !!!
