i have scored 125 in aieee which college i will get

Your marks in AIEEE is 125 which means your All India rank would be around 45,000-50,000.

To take admission in any NIT,you are required to get at least rank of 25,000.

So,with this rank,you can't get any NIT this year if you are from general or OBC category.
If you are from SC/ST category,you will easily get an NIT.

So,you can try for other government colleges if you don't get NIT.
