Yes, I concur these things will come up to your psyche, however finding a correct solution to this is not in any way conceivable, as this likewise relies on how others performed in the exam however I figure you would be getting a rank to some degree around 10k yet who knows, anything can happen yet with a rank of fairly around 10k, you will have the capacity to get a portion of the branches in the recently opened up IITs, so yes you can plan to be an IITian soon.
