Hello Aspirant,

See for JEE-Advance 2022, there is no requirement of top 20 percentile for any of the board but what you need is just you should have passed the class 12th even for admission to NITs/IIITs/GFTIs also there is no any such requirement. This relaxation is given in the wake of pandemic for current academic year.

Also note that maximum attempts allowed for JEE-Advance is 2 in 2 consecutive years, first attempt in the passing year of class 12th or equivalent examination and second attempt in very next year to that. Similarly for JEE-Main maximum attempts allowed for JEE-Main is 3 in 3 consecutive years, first attempt in the passing year of class 12th or equivalent examination and second attempt in very next year to that followed by third attempt in third year.
