Hello! Hope you are doing good

It all depends on the difficulty level of the paper. If it was easy and too direct and your score wont fetch you any IIT. If it qas a bit indirect and difficult for the masses then you have good chances of getting into an IIT. Assuming your score and the previous years trends you can go ahead with geomatics or earthquake engineering and even orher courses of your choice or something that you qualify for.
