There are two ways to complete the exercises in this book. You may choose to work directly from this book, or you can perform the exercises onscreen. To complete the exercises onscreen, follow these steps:

1. After installing the exercise data files, an icon will appear on your desktop.
2. Double-click this icon.
3. Follow the onscreen step-by-step exercises.

The onscreen exercises are the same as those found in this book. An advantage of working onscreen will allow you to concentrate on the exercises without having to glance down at your book.
