hello aspirant,

I hope that you are doing absolutely great.

With reference to yoru above mentioned query, I would like to tell you that yes, you are eligible for JEE mains 2022 even if you've passed from nios also.  Students should have passed the 12th class or qualifying examination. Candidates appearing in 12th class or equivalent qualifying exams can also apply.
