Hey Chandra!!

Please mention your home state. There are chances in your home state(the state from where you passed your class 12th from) because the cutoffs for home state candidates in relatively lower as compared for outside state candidates. So, if you are fortunate enough, you might as well land in the NIT of your choice but I am sorry to say that you have no chance for admission in top NITs and IIITs because the seats fill at 10000 max even for their home state candidates. So, I would recommend you to look for the branch of your interest now because if you are aiming to get CS, mechanical or ECE it would very difficult to take admission in NITs. So choose wisely!

All the best for your future!!
