I agree with Dan on this point about the Electrical test. It was in my opinion the hardest test of the four and I, too, was surprised I passed the first time. The study guides were a big help to me, I didn't try the home study course, but if I were to do it over, I probably would have used it even though I passed all tests on the first attempt (probably by the minimal score when it came to the electrical

). I didn't think the tests were easy (even being open book), but definitely passable with the right preperation.
Even though as Scott said, it is not necessarily a test of your knowledge, existing knowledge of the codes will definitely help as it is a timed test and if you already know the answers to some of the questions, it will free up time for the ones you have to look up.
