Hi Spencer, The most difficult part of the exam for me was the law of knowing about filing liens, preliminary notices etc . .although I've only had to take 1 person to court in the last 30 years, won the case but never did get paid due to their Bankruptcy , The trade part of the exam was code based and had a lot of blue print details. The positives do out weigh the negatives. I did give the business a break after the first 14 years decided to join the Ibew, took their journeyman exam which was a 5 year program based on one 4 hour test, that was more trade extensive I thought than the CSLB Exam.
Anyway not to share my whole life history but the Ibew was good for 10 years, met a lot of great electricians loved the team spirit but it was very political, when I left they had over 1000 of us sitting on the books for a year, decided it was best to depend on my own efforts, dusted off the ol' C10 license and have been at it again for over 10 years now. End note : you picked a great Trade, it will provide well for you, just always respect electricity, always be cautious and never lower your guard. , it is not forgiving and is always ready to complete the circuit.
