Dear aspirant,

There is no pattern in any IIT for setting the paper of JEE advanced. Professor there are given some topics and some some subject to come up with their questions within the syllabus of IIT JEE after that the committee select the question and craft the paper.

It is believed that IIT Guwahati sets a tough paper but that is not the case every time it's just an assumption but not with enough proof. I suggest if you are preparing for advanced get your hands on some good material and practice daily for 4 to 6 hours for one year to get a good rank.

Thank you.
