We won't fake testimonials. Here's what we can prove instead:
- 292 practice questions, every one tagged to its NEC article with a worked solution.
- Built for TDLR's 2-part split (NEC + Calculations) — mirrors the official topic mix, not the old single exam.
- No "real exam questions" gimmick. Nobody has TDLR's bank; anyone claiming to isn't being straight with you.
- Every answer carries the exact NEC article it tests, hand-checked against the code. No AI-guessed code references that send you to the wrong rule, no "you were wrong" with no explanation.
- 30-day money-back. One $99, free NEC 2026 update — low risk to try.
On electriciantalk and the Mike Holt forums, the same point comes up again and again: if you can navigate the NEC and do basic calcs, you'll pass — the time limit is what gets people.— recurring forum consensus, paraphrased

Are these the actual TDLR questions?
No — TDLR doesn't publish theirs. These mirror TDLR's official topic mix and difficulty. Anyone selling "actual TDLR questions" isn't being straight with you.
Are the answers actually accurate?
Every question carries the exact NEC article it's testing, with a worked solution — checked by hand against the code, not generated by an AI that guesses article numbers. If a reference is ever off, tell us and we fix it.
