The journeyman electrician exam is open-book, but most people who fail don't fail on knowledge — they fail on speed, running out of time cross-referencing two or three NEC articles per question. Loomi is designed around that exact bottleneck, with lookup-speed drills and spaced repetition tuned to the articles you're weakest on.

Everything here is scoped to the journeyman license exam — not the master or contractor exam — and covers NEC 2017, 2020, and 2023 so you can prep against the edition your state actually tests on.
