Progress Test 1
This Progress Test covers the course materials that were assigned in Units 1 and 2. Although the progress test is
similar in style to the unit evaluations, the progress test is a closed-book, proctored test. You may not have access
to notes or any of the course materials while you are taking the test. It is important that you do your own work.
Select the response that best completes the statement or answers the question.
You may use your calculator or scratch paper to work out solutions.
