Hello student.

27,00,000 rank is higher one to get seat in the top nit or iiit colleges. But since you have mentioned that you belong to the obc category you may have a chance of getting into some good nits though we cannot say for sure that you will be guaranteed a seat at nit rourkela.

I suggest you to apply for state colleges or any other private institutions. There are pretty many good private institutions where you can apply. Here are few good private institutions

1. Ssn college in chennai

2. Amrita institution in coimbatore

3. Psg college of engineering in coimbatore

4, cbit college in Hyderabad

5. Vasavi college

6. Sastra deemed to be a university in thanjavur
