The Problem
The exam isn't about memorizing the whole code book. It's about finding answers fast. Article 310 conductor ampacity. Chapter 9, Table 1 conduit fill. 250.66 grounding electrode conductor sizing. If you can't navigate the NEC under the clock, you're paying to retake a $75–$150 exam.

Voltage drop. Box fill. Conductor derating. Motor FLC. Free points if you've drilled the method. Score killers if you haven't.
Open book or closed. NEC 2020 or 2023. Different vendors. Local amendments on top. Prep built for a generic exam leaves gaps exactly where your state differs.
