2613 rank in BC category may not bring you the streams of your choice, but there is a possibility that you get a chance into jntuk for other courses. Just wish that most of the rankers get good Central Universities and they join there so that you could fulfill your dream.

One must always have a plan B so should you, You can apply for the same streams at AU, JntuV, some other government colleges. I'm sure you will find the engineering stream of your choice there for sure. Make sure you fill the counselling preferences well because that'll decide your future.

All the best.
