  1. Select the class whose levels you want to view under the 'Classes' tab on your Dashboard.
  2. Once on the Class page, select 'Practice Settings'.
  3. There you will see all the levels currently enabled for this Class.
  4. Select 'Edit' to add/remove levels for this Class.
  5. Select 'Save'.
