Hi..
First of all I would like to congratulate you for a good performance in the exam
Now, with this rank you might have to compromise with any one of the two-either your branch or the first seven good IITs.
It depends on your interest now. If you are very much keen for one or the other branch, you should go for that. Else you can prioritise the college first and then look for some random branch.
Hope you take a wise decission.
Regards
