Hii There,

You have a good chance of getting admitted to different NITs (National Institutes of Technology) if your JEE Main OBC category rank is 30,000, especially in fields other than the most competitive ones like computer science engineering (CSE) and electronics and communication engineering (ECE).  Your chances of being admitted are further impacted by the fact that you reside in Maharashtra.

Candidates with your rank may be eligible for branches like civil engineering, mechanical engineering, or chemical engineering at institutions like NIT Warangal, NIT Rourkela, and NIT Silchar.

Here is the list of top engineering colleges in Maharashtra

I hope this answers this question.

Thanks
