How do I restart a module to let a student redo it?

A module can only be redone if the student has failed it. Then, they are allowed to redo it and submit again for a new score.

Once a module has been submitted, graded, and passed, it cannot be restarted or redone for a new score.

That said, students can still continue to practice freely in the simulator regardless of whether a module has been passed or failed. Practice access is not restricted by module results.

If your goal is simply to clear the current scan setup during a simulator session, you can do this without affecting the module by clicking New Scan in the simulator view (top-right corner). This clears the sequence tray and allows the student to start a fresh scan setup.
