Brother, it would be easier for me to guide you, if had told your JEE advanced marks.

Though, from your category rank, it appears not only you have qulaified JEE advanced but you have managed to get a seat at new IIT's.

So, I would recommned you to explore your niche/interest, so that you can explore the branch in which you are interested the most and this would help you in ease out your counseling.

Thank You
