Hello Aspirant,

Yes you can definitely get admission in any of the NITs or IIITs on the basis of your JEE-Main score even if you have not secured 75% in class 12th because for this academic year the 75% criteria has been waived off just like that of previous year.

So now you only need to pass class 12th in all the subjects and you will be eligible for admission on the basis of your JEE-Main score.

But note that this criteria has been waived off only till current academic year for now so don't consider it for next year because next year it might get restored depending upon the circumstances at that time.

Good Luck!!
