Activity Diagram and Fully Developed Use Case Description of USEP's Pre-Enrollment System

The Activity Diagram that is shown below is composed of the Use Cases that I mentioned in my Assignment 7 in SAD. The Activity Diagram shows the starting state of the activity, the flow of the works from different actors, and the end of the activity in the Pre-Enrollment System in USEP.

Based on the report on Modeling System Requirements which is my assigned topic, I reported the Fully Developed Use Case Description of a specific system. In a fully developed description, it includes the use case, the scenario of the use case, the triggering event, a brief description of the use case, the actors and stakeholders, its preconditions and postconditions, the flow of activities, and lastly the expectation condition. Here are the use case description for the use case that I mentioned in the Pre-Enrollment System in USEP.
