Most state Journeyman exams have 80–100 questions covering NEC code, wiring methods, branch circuits, motor controls, and load calculations.

Most states require a 70–75% passing score. This practice test uses the same 70% pass threshold so you know where you stand.

Questions are written to the 2023 NEC. Check your state licensing board to confirm which edition your state has adopted.

Decent site but some of the questions feel a little outdated, not sure if they are updated for the 2023 NEC or an older edition. Still usefull for getting familiar with the code format. Would be better with more state-specific questions.

I've been studing for my journeyman for about 3 months and started using this site maybe 6 weeks ago. Big difference in how confident I feel going into the exam. The explainations after each question are really what sold me on it.
