Hello Anshu, Greetings!
Well, although getting a NIT tag would be great but taking another drop for it would not be a good idea.
I think you should continue your studies in BIT Sindri. It is also quite decent college and you will also have core engineering branch. Although the fees is on a bit high side but the placements are quite good.
In the end, it's all your choice. So, make your decision wisely.
Thank you, best of luck.
