Why this site exists
Knowing the code isn't the hard part. Finding it under a clock is.
Most journeyman exams are open book. You are allowed to bring the NEC, so the test is less about memorizing rules and more about doing the calculation correctly and finding the right table before time runs out.
This site exists to give apprentices and electricians getting ready for that exam the reps they need: a large bank of exam-style questions, explanations that show the work, and a code reference on every answer so you can practice the lookup itself.
It's built to be used alongside your own codebook. Your account remembers every score and every question you missed, so you can pick up on your phone where you left off on your laptop.

What's covered
Seven topics, color-coded like the conductors in a cable

Calculation questions are generated from NEC tables and standard formulas, so every number can be checked in the codebook.

Read the NEC free online
NFPA, the organization that publishes the National Electrical Code, lets anyone read the NEC online for free. All you need is a free NFPA account. The free version is read-only, so you can't print or download it, but you can browse every chapter, table, and annex.
Use it if you don't own a printed book yet. It's also useful practice if your state or testing center provides the codebook on a screen instead of on paper: finding a table on a monitor takes some getting used to.
Pick the same edition your state has adopted, and keep it open in another tab while you work through practice questions here.
