California contractors who passed
Load calculation questions were the hardest for me. The diagrams in the study guide showed me how the parts connect, and after that the practice questions made sense.
Some of the code language is hard even for people who speak English at home. The guide explained it in normal words.
Two weeks of practice exams after work and I passed.
