The process is as follow:
- The use case begins when a student accesses the course registration system.
- The student logins to the system by entering his/her Baylor ID and password. The system verifies the login information.
- After the login information is verified, the system then displays all the available options (i.e., add class, delete class, and view class). The student selects "add class".
- The system prompts the student to enter the course ID. The student enters the course ID.
- The system returns the results and displays all the available sections. The student selects the course and select "next".
