Hello aspirant!

No there isn't any percentage criteria required to give JEE mains. However, admission into IITs, NITs, IIITs and GFTIs you need to have 75% aggregate in your class 12th board exams or you should be in the top 20 percentile of your board exams. For other state government colleges and private colleges, you need to have an aggregate of 45% in boards.

Hope this helps.
