Training Lessons On the following page, you'll click a start button which will open a separate browser window for the training section of the course (if this window does not pop up, enable pop-up windows in your browser's settings). Complete each lesson and click the next lesson's link at the very bottom of each lesson page. A checkmark will display next to the lesson names in the sidebar as they are completed. At the end of the last training lesson, you will see instructions for exiting the lessons and navigating back to the original browser window in order to complete the course.
