Does IIT Madras make tough gate paper

This year GATE is being conducted by IIT madras.Before this GATE 2011 conducted by IIT madras.As it is expected by student that pattern and quality is set by organizing IIT,But this is not true,GATE paper doesn't depends upon organizing institute.Oragnizing committee request different paper set from different IITs.At last common paper is finalize by organizing committee.Quality of paper doesn't depends upon organizing IITs.
BEST OF LUCK!
