A regulation defines the set of courses that will be offered to a cohort of students of a program. For example, students starting their B.Tech CSE program in 2016 may have had a set of courses that will be different from another set of students taking the same course in 2020. A regulation offers a way to define this difference.

A subject is always defined with its corresponding regulation. When regulation changes, new subjects will be defined with new subject codes.
