In other words, if you use them in a training class, it takes two days to complete the course. However, we have structured them so that each day of training can stand on its own. In other words, Part 1 is the first day of the training class and Part 2 is the second day.
Some people prefer to run one-day classes.
Therefore, you can buy just Part 1 if you wish. Later you might decide to come back to buy Part 2 so that you can run the second day of training. Most people buy the full course rather than buying each part separately. With the full course, you get both parts bound together as one manual. I thought the Full Course meant the introductory course plus the advanced course For many software products, we write an introductory course and an advanced course.
