It is critical that you take the time to read through the Summary of Key Concepts section on pages 192 - 198 of your text. Read the introduction to each section and then study the examples as they are presented in your text. Only after you study these examples carefully should you proceed to the Practice. Remember, you are not responsible for the work in Section 3.3 in your text.
The Practice exercises on page 199 - 204 will give you a good indication if you have mastered the outcomes intended for Unit 03. If you have difficulty with any of then, you should contact your teacher before you proceed to the next unit.
There is no self test for this lesson.
