Use Case for USEP Enrollment System??

This is a brief use case diagram for the USEP enrollment system. This is only applicable for students in their second year and onwards.

As perceived in the figure above, a student has to pass several stages in order to reach the completion of the enrollment process. The first of which is the payment of local fees,of which from my observation is done manually or without the help of any machine or computer for recording the payments. The second step is the evaluation of grades and subjects by an adviser, whom in return will present a PRF to the student. The PRF will then be given to the encoder who will present an official PRF or COR to the student. The student then proceeds to the cashier who will receive the payment (if student is not a scholar) and record it in a financial system. Students who are scholars are referred to the bookkeeper for validation. Then, the student is ushered to the Registrar where the student is to present his/her clearance and necessary receipts so as to mark them as officially enrolled students and have it recorded in a registering system. Lastly, the student is to present the marked/validated COR to the Librarian with his/her library card for validation.

I am not really sure whether what I presented is what was really required. But then since everyone thinks on the same trail as mine this is the diagram that I will present.
