2A practice questions - frequently asked questions

Plain answers about how 2A 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 2A exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The 2A exam spans 9 domains: Cabinets, Panelboards, Switchboards, Boxes, and Conduit Bodies; Calculations of Load; Calculations of Wire Size; Conductors and Overcurrent Protection on the Load Side of the Service; Lighting and Utilization Equipment; Service Equipment and Conductors on the Supply Side of the Service; Special Installations or Constructions; Switches, Disconnects and Controllers; Wiring Methods. Every practice question on this site is tagged to one of these domains.

The 2A exam has 50 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
