Click in the circles to select your answer. When you push submit at the bottom of the page, the program will score your test and mark the right answers with a red star and also tell you where to look up more information about the questions that you missed. The program will not tell you the right answer if you missed the question. Your answers on this test are not recorded nor are they sent to the instructor.
