Well brother, at this socre you might have cleared JEE advanced. So, firslty congratulations for this. 

Now addressing the question, it would be almost impossible at this rank to expect a seat at IIT.

yes brother, this is the harsh reality of JEE advanced. You have cleared it but still it brings no benifit in terms of admission.

So I would recommend you to opt for a college on the basis of your JEE mains scorecard or to prefer Rajiv Gandhi Petroleum university (if you have interest in petroleum).

Thank You
