What is the difference between test and tutorial mode?

Test Mode: After you set the number of questions you wish to include in your test, the system delivers each question one at a time.  Once you have completed all questions, you will receive a grade for that session and then be able to individually review each question for that session. 

Tutorial Mode: After each question, you will see whether your answer was correct and receive the rationale for the answer before proceeding on to the next question.
