Is the JOURNEYMAN exam different depending on which state you take it in?

Relocating from one state to another in a few months and trying to figure out if my Journeyman Electrician’s Exam prep needs to change based on where I'll be taking the actual exam.

I've been studying "what is a journeyman electrician" and the materials seem standardized, but I've heard the exam can vary by state or have different question weights.

Specifically wondering:
- Are passing scores the same across states?
- Does the content on how to become a journeyman electrician differ by state?
- If I pass in one state, does it transfer?

The official resources are confusing on this. Some say it's a national exam, others suggest state-specific versions exist.

Anyone who's taken JOURNEYMAN in multiple states or knows how the portability works — would really appreciate the clarity before I invest more time in state-specific prep.
