dear manoj kumar,
though your AIR rank is very high but your state rank is decent..I think you may get any of NIT of any brnch may be metallurgy becoz the people before your state rank may join in IIT and in BIT's so by this you have a scope of getting a seat in any of the NIT's so dont worry you have a chance of getting a seat in NIT lets hope so...
