Journeyman or master?
In Virginia, Iowa and Texas a master license comes after time as a licensed journeyman, and the master exam is longer. In Texas, for example, a master can directly supervise apprentices on any job site.
Preparing
Get your state's bulletin first, since it names the code and the topics. Then practice with questions and, for an open-book exam, with your tabbed code book.
