What is the difficulty level of GATE papers when set by IISc Bangalore?

No single institution sets the GATE papers. A group of professors from different IITs, NITs, and IISc Bangalore set the paper. Each year an institution gets the responsibility of selecting the professors for question paper setting. This institution also looks after other administration-related work.

I would suggest you practice the previous 10-20 years’ question papers. Also, do not try to assess the difficulty level of the upcoming GATE exam by looking at the previous years’ trends, as it will not help.

Practice well for your GATE exam and make a note that GATE papers will not be set solely by IISc Bangalore or any one institution.
