The chapters are organized to be independent of each other so that you can study only the ones that relate to your errors. Based on your writing, your teacher or tutor may assign chapters, or you can determine whether you need a chapter by taking the Pretest and letting the computer analyze your errors. The analysis will tell you what parts of the chapter you need to study. Then you can take the Mastery Test at the end to see whether you need to review sections and get more guidance from your teacher or tutor. The results of the Mastery Tests are e-mailed automatically to your instructor.
Another way to select Part Two chapters for study is to keep track of the errors that show up in the writing that you've been doing during the course. If your teacher or tutor marks your papers using the Correction Key (Chart 15) in Part Four of the Study Guide, you can enter the number of errors in each category for each paper. After a few papers, you will see which chapters you need to study.
