Re: Journey exap
Being able to find those answers as quick as possible is a skill developed through practice, much like an athletic skill. After a lot of practice you can read a question and know which place to look first--your tabs, the index, or the table of contents. All have their place. I used Mike Holt's Exam Prep book to study the steps for the calculations--load calcs, voltage drops, wire fill, sizing, motors, x-formers, etc. and to get saturated with NEC q's. As you spend hours looking up questions, both easy and hard, you remember where things are, and these things will come back to you when you answer other questions. As the exam got closer, I used Tom Henry's master's workbook with the 70 question NEC practice exams. I timed myself at strict 2 hours, and it was very hard to finish them. By the time I finished the 12 exams, I was doing them with time to spare and scoring in the 90s.
Although you should thoroughly learn how to do all the calculations before the test, remember that if you get stuck in the middle of the test, "Annex D" in the back of the code book has examples of a lot of calcs, and you can always refer to that.
