Well, brother I know you have studied quite sincerly for getting this rank.

But now I would like to introduce with the harsh reality of life. The reality is you won't be getting any academically suitable college at this rank.

Yes brother, at this rank opting a very poor NIT is undoubtedly can be your worst decision in life. 

I would recommend you to opt for a state engineering college or if you are willing to excel, then you can reattempt the JEE mains in next year.

I would recommend you stay positive and opt for the best available option

feel free to ask for any further query
