Hello student ,

The eligibility criteria says that for JEE Main, you need to score minimum 75% score (if you belong to open category) or must be in the top 20 percentile of your board (Bihar Board included) for admission into IITs, NITs, IIITs, and CFTIs. Further for another institutes, the minimum requirement may vary depending on the individual eligibility criteria set by institutes that use JEE Main scores for admission.

Hope it helps !
