I am also in TN and ordered the ethics test from the AICPA Website. I ordered the book version because I seem to do better with an actual book to look through. The questions that are in the back of the book can be torn out, and I found that the questions follow along right along with the book. After you believe you have all the correct answers, there is a website provided where you enter your answers and then it will give you the results (if only the actual exams were like this)! You have 3 attempts to get 90%. It will show you what answers were correct & which ones were wrong.
Hope this helps!
