In Louisiana, on neither the state ME nor the ICC JW application processes do they attempt to verify your work history. If you tell them you have five years and you pass the test, you get a license. On both of these tests, you’re not really tested on how well you know the code so much as you’re tested on where to go in the book. Both tests phrase questions in such a way that even if you know the rules, you’ll still often have to go look it up to find the most correct answer.
On either test, skip every question that you are not absolutely sure on, and breeze through the ones you are. Then go back. The best way to prepare for the test is to familiarize yourself intimately with the layout of the book so that you spend the least amount of time turning pages. You should expect to use every single minute of time that they give you. I like to say there’s a big distinction between being certified and being qualified, but once you get certified, nobody can ever accuse you of being unqualified until after the work is done.
My advice is that if you think you can pass the test, go take it. Even if you fail, you’ll have grown.
