Hi Suraj,

At this rank, you won't get admission in top NITs. Though you can get admission in some of the lower ranked NITs like Agartala, Nagaland, etc. I would suggest you to use college predictor so as to have a better view of all the options available to you.

Well brother, I can understand your situation. I know you have worked hard for JEE mains but I believe with 100k rank you won't be getting college. 

Though with OBC and home state quota, there might be an increased chance of your's getting a seat but with such a rank it is very hard to get.

So, I would recommend you to take part in JoSAA and go to through all the round even the spot round

Thank You
