The Washington test has a theory section, series, parallel circuits...
I would look for the following from your state licensing agency
1. What does it take to qualify for the electrical exam?
2. What are the tests based on and recommended study materials
In Washington you must have 8,000 hours of documented experience as a trainee or be an apprenticeship school graduate. In a few years anyone wanting to be a Journeylevel electrican must be an apprenticeship school graduate, no more learning on the job. The first time pass rate for on the job journeylevel applicants is about 55%, for residential electricians (4,000 hour specialty) its about 22%, which is sad.
I used to get a lot of emails from carpenters, technicians, CAD, who taught they could take a few classes and become an electrician.
