Forget about any testing for certification at this point. Get into some sort of apprenticeship program, Union or ABC or any sort of recognized program. Work at the program, take the classes, learn the codes, learn the methods, etc.
Once you have completed the program you would THEN (IMO) be ready to take a Journeyman's test. Forget about the Masters until you've worked in the trade for at least 5 years. (that is usually how long it takes to be a journeyman).
The important thing is to GET FIELD EXPERIENCE!!!
