Hi !!

As of now, there has been no official reporting of any

wrong question in IIT JEE 2011

by the organizing committee or any other educational/ general institution.


However, if there was a glitch, then the IIts would definitely take a step in that direction to rectify the mistake.

So, you can stay assured.
