EC practice questions - frequently asked questions
Plain answers about how EC Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.
No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real EC exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.
The EC exam spans 9 domains: General Theory and Electrical Principles (19-21%); Plan and Specification Reading and Interpretation (7-9%); Wiring and Protection (13-15%); Wiring Methods and Materials (11-13%); Special Occupancies and Situations (13-15%); OSHA, Safety, Procedures for Testing and Use of Tools and Equipment (8-10%); Life Safety and Americans with Disabilities Act (4-6%); Electrical Signs, Outline Lighting, and Structural Considerations (2-4%); Alarms/ Limited Energy (14-16%). Every practice question on this site is tagged to one of these domains.
The EC exam has 150 questions and is completed in 7 hours 30 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
1,000+ questions across all 9 EC exam domains, mixing scenario-style multiple choice with true/false drills, each with a plain-language explanation.
Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That is the difference between hoping you're ready and knowing where you stand.
Yes - 10 free questions with full explanations, no card and no signup required. Start on the home page.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and (on Fast Track and Pass Confidence) progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window. Nothing renews, and no card details are stored for future charges.
Match it to your exam date: Final Review (2 days) for an exam in the next day or two, Fast Track (7 days) for an exam this week, Pass Confidence (6 weeks) for a structured run-up. See plans and pricing.
For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is built mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.
Make sure you're signed in with the same email you used at checkout - access activates within a minute of payment. If it still doesn't appear, email support@boardmentor.study and it will be sorted out.
Yes - 24/7 chat support, right from the chat bubble in the corner of every page: instant answers about plans, access, billing, and your prep. Prefer email? Write to support@boardmentor.study and a real person will reply.
