First of all congratulation for your good score in jee main. You can get your state government collegs with rank other than that you can only get private colleges . Your chances for nits are very rare. Only you can apply to your home state nit. Best of luck. 

Hello Abhilash!

According to the last year cutoff trends you may get a seat in lower NITs or GFTIs if CSAB special round is conducted. The cutoff falls drastically during special round so the possibility of getting a seat is high. But for that special round must be conducted like last year.

Hope that helps!
