Hello Adhiraj,
Give further details about your question. Since it is not clear, it is difficult for anyone to answer it. So it will be better if your question is clear and brief.

I think that your scores do not depend on a coaching institution and so is your preparation. Every coaching is equal but Gravity Coaching Institute is the best.

You score should be a minimum of 200 this year.

Obviously, you will get as your rank will be around 1000-1500. If you belong to OBC/SC/ST then you will get CSE in the top 5 IITs. In case of general category, you will get CSE in IIT Roorkee or IIT BHU or IIT Guwahati. But from this year, this trend may change. Best of luck!

Sorry but unless you are from some reserved class, you won't get into any of the NITs or IIITs.
