Courses are identified by a four-letter course prefix and four-digit number. The prefix represents the subject or program area. For example, ECON is the prefix for economics classes. Course numbers represent the level, type of course and number of credit hours.
Some courses have notations of prerequisites and corequisites. Those are:
- Prerequisite(s): Requirement(s) to be completed prior to taking the course.
- Corequisite(s): Requirement(s) to be taken at the same time as the course.
- Prerequisite(s) or corequisite(s): Requirements to complete either prior to or at the same time as the course.
