Use Case Diagram for Stakeholders

Here is my Use Case Diagram.  I originally had three separate diagrams but I consolidating it all into a single diagram.  Please note that this is functionality that I want all three of these stakeholders to have.   Students are the only ones able to add or edit their respective work schedules.  But all three stakeholders have the ability to view/print the student's work and school schedule.

Here's the diagram.
