  2. Initialize or Check Semester

    • Retrieve the current semester.
    • If no current semester is found, create a new one.
    • If the current semester exists but has ended, create a new semester and increment student levels and semesters.
    • If the current semester is active, log it as active.

  3. Get Student Balance for Semester

    • Retrieve financial statements for the student for the specified semester.
    • Calculate the balance and credit from the latest financial statement.

  4. Increment Student Levels and Semesters

    • Retrieve the student balance and credit for the old semester.
    • Calculate the amount to roll over.
    • Calculate the new level for the student.
    • Update the student's level.
    • Assign the new semester to the student.
