You should get metallurgy in NIT Tirchy, but dont expect it before the SPOT Counselling
As I have mentioned earlier as well
Cutoffs of NITs are expected to be on the higher side as private colleges like LPU etc have not been allowed untill the fifth round.
Remember SPOT Counselling after the fifth round is most crucial. 23 new private colleges including Amity (Noida,Lukhnow,Jaipur Campus) and LPU would join the counselling then. Cut-off of NITs against the vacant seats would fall drastically then
