Where does it live?
The code half of the exam is open book. The answer is in front of you. What runs out is the time you spend deciding where to look, so this drills only that.
The article level moves are concentrated at the two ends of the book: Chapter 1 took in load calculations from Article 220 and energy management from Article 750, and the limited energy and communications material was rebuilt across the 720s. Ampacity, overcurrent, grounding, motors and boxes kept their articles, and Chapter 9 is still the tables.
A question appears in the wording an exam would use. You name the article. It is scored in seconds, because seconds are what you are actually short of.
Some of the wrong answers are article numbers that no longer exist. A few died this cycle. Others have been dead for years and still turn up in old study material. Those are the ones worth getting wrong here rather than in the exam room.
