Hello Kaushal, honestly speaking you might not get an admission in any NIT , but keep your fingers crossed and have faith in yourself , i think you can easily qualify for JEE Advanced , give your best in that exam and you might end up in an IIT. But as far as the NIT admission , it is a bit certain that you might not end up with a NIT seat. Unless you can compromise with a certain NIT's and certain branches. Just have trust and faith in yourself .

All the very best for your future endeavours and wishing the best for you.
