I hope you're doing well, Aspirant.

Sorry to disappoint you, but a seat at NIT Warangal is impossible to obtain at this rank, as the closing rank is between 2k and 4k.

You can apply to private colleges like Nirma University, Thapar University, DAIICT, PDPU, and others that accept JEE MAINS scores. I hope this information is useful!! Best of luck!!
