Hi!! Yes you can admission in NITs and IIITs. You haven't specified any branch preference and your home state so I am just giving you a few suggestions:

Firstly give preference to NIT over IIIT unless you wish to pursue IT obviously. Some possible options in  NIT for you are:

1. Metallurgy in MNIT,Jaipur

2. Metallurgy and mining in VNIT,Nagpur

3. Metallurgy and mining in NIT,Andhra Pradesh

These are just a few suggestions. You will have to go for metallurgy or mining in NITs since getting a seat in other core branches will not be possible. If you don't want these branches then IIIT is the other option for you. So if you want IT then go for IIIT or else go for NITs. Remember that you can always change branch after getting into college. Think well and decide what's best for you.

Best of luck!
