Progress Test 1 (Evaluation 51) 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 test. You may not have access to notes or any of the course materials while you are taking the test. *You may also use your graphing calculator on this test.*

The Summary of Formulas and Trigonometric Tables from the Appendix is included for your use during the test.
