How are the papers set by IIT Madras like?

A few of my friends graduated from the IIT Madras and here are some points related to your question that might help you. I am assuming that you are asking about the course papers.

• It is a common misconception that the paper is set by a single IIT.
• Every year the question paper is always set by a team of professors chosen from different IITs.
• Various sets of papers are made and finally, one set is chosen by the head of the committee.
• It depends on the specific subject and the paper setting committee.
• The Mathematics paper is well balanced with Algebra, Analysis, and parts of Applied Maths and topology.
• The questions are subjective with a check on your understanding of the concepts and proofs.
• If a person is good at Algebra and Analysis, one can get through the paper.

You do need to remember some basic things like the Papers are regular like you had in school. The questions are from the course curriculum. You can of course expect a basic level of difficulty in the questions. Everything depends on the course and the faculty. It can get very easy and it can get difficult, according to that.
