Each of these classes, with the exception of the All Natural Homemade Medicine Cabinet, have tests within them which, once completed, are sent to the instructor Christina M. Schumacher. These tests are not graded, however, they do allow you to know that you are understanding and learning the information as you are meant to. Questions are also always welcome.
