The Data is set out in five sections. It is laid out to allow you to formulate a study plan. We suggest you work through each section and check your progress on the various knowledge checks. Our experience shows that everyone learns in a different way, so consider using maps, visual markers on maps, lists, and even physical observation and route driving.

This is designed as an on-line package but with GTL, you still have the confidence that someone who knows the job is available to contact for help or support.
