Each class has a corresponding code. These codes are determined by three factors:
- A four-letter code that categorizes the class according to which subject it belongs. (For example, a class labelled "BIBL" belongs to the subject of Bible.)
- A four-digit code organizes classes within each subject. The first number indicates the level of the class ("1" marks a freshman level class, while "4" marks a senior level class), and the last (fourth) number indicates the number of credit hours one may earn from this class.
- A two-digit code will appear at the end to indicate the class section only when there are multiple sections available for one class.
Below is a list of the four-letter codes and their corresponding subjects.
