Can You Bring Your Own Code Book to the California Electrician Exam?
This is one of the easiest places to get bad advice, because old forum posts and old prep pages still talk about personal code books and tabs. Read the current bulletin before you test.

What the bulletin lists for General Electrician

How to study when the book is provided
You still need to know where rules live. You just cannot depend on your own markings. Build a mental map of the book: 210 for branch circuits, 220 for load calculations, 250 for grounding and bonding, 310 for conductors, 314 for boxes, 430 for motors. That map is faster than wandering through a clean reference.
- Drill article families without tabs.
- Practice index keyword selection.
- Write calculations cleanly using the online calculator rule in mind.
- Use timed sets so slow lookups show up early.
