The exam prep that
actually answers you back.

It depends on which exam. The General Electrician (Master) certification exam is semi-open book — the NEC and certain reference materials are provided at the testing center. The C-10 Contractor license exam (Law & Business + Trade) is closed book, administered on computer at a PSI testing center. CertifyPro prepares you for both, teaching you to work quickly with the code when it's available, and to know the key rules cold when it's not.

The General Electrician certification exam has 100 questions with a 4-hour, 30-minute time limit. You need a 70% to pass (70 correct). The C-10 trade exam has 115 questions with 210 minutes. That works out to roughly 2.5 minutes per question — time pressure is real, and learning to move fast is a core part of what CertifyPro trains.

70% on both exams. For the 100-question General Electrician exam, that's 70 correct answers. You'll get your score immediately when you finish — no waiting. CertifyPro's sim exams won't let you stop until you're hitting 80%+ consistently, giving you a real cushion on test day.

60 days from the date you failed. You'll need to submit a retest application and pay a $100 fee. You have up to one year from your eligibility notice to pass — if that window expires without passing, you have to reapply from scratch. That 60-day wait is expensive in time and money. CertifyPro is designed to get you through on the first attempt.

The bulk is National Electrical Code (NEC) — grounding & bonding (Art. 250), branch circuits (Art. 210), load calculations (Art. 220), overcurrent protection (Art. 240), motors (Art. 430), and services. The C-10 exam also includes California Law & Business: contracts, bonds, Cal/OSHA, CSLB rules, and workers' comp. CertifyPro's 18 modules cover every topic, weighted by how often it actually appears on the exam.

Most people are ready in 4–6 weeks studying 1–2 hours a day. CertifyPro's 6-week roadmap structures exactly that — starting with high-frequency topics, building to sim exams in the final week. If you already have strong NEC knowledge from the field, some students move through it in 2–3 weeks. The AI Tutor and readiness score tell you when you're actually ready, not just when you've finished reading.

No — phones, laptops, and tablets are not permitted at PSI testing centers. CertifyPro is a study tool, not a test-day resource. What it does is train you to find things fast in a physical NEC codebook and memorize the rules that come up most often — so when you're sitting in that room with just your codebook, you already know exactly where to look.

One payment. Lifetime access. No subscription. You get all 18 modules, the AI Tutor (unlimited questions), the NEC Navigator, timed sim exams, the 6-week roadmap, and the formula cheat sheet. If you have to retake the exam after the 60-day wait, you still have full access — no repurchase needed.

For the General Electrician exam, the NEC is provided at the PSI testing center — you don't bring your own. That said, studying with a physical copy as you go through CertifyPro is strongly recommended. You want to know the book's layout cold before test day. A 2020 NEC runs $100–$120 new, or you can often find used copies for less.

Two things: price and the AI Tutor. Thompson Learning charges $160/month. Mike Holt runs $85–$150+. Neither has an AI that answers your questions in real time. When you're stuck on a motor calculation at 10pm, CertifyPro gives you a direct answer with the NEC article cited in seconds. No other exam prep in this space does that — at any price.
