A minor is obtained when a student does a minimum of 4 courses from the set of courses offered in a particular field. Minors cannot be from the same branch that the student is majoring in. IITM offers minor programs in various fields, ranging from sociology, philosophy, and economics to Artificial Intelligence and Machine Learning. They are acknowledged on the transcripts and serve as proof of your proficiency in the secondary field.
No, minors are not compulsory at IIT Madras. They are completely up to one’s interests and goals.
