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

The OR-JE exam spans 15 domains: Electrical mathematics; Safety and accident prevention; Care and use of hand and power tools; Blueprint reading and electrical symbols; Introduction to National Electrical Code; Electrical fundamentals and basic theory, including AC and DC; Electrical measuring devices; Wiring methods; Low voltage and limited energy circuits; Residential, industrial and commercial calculations; Motors, generators and transformers; Practical circuit sketching; Lighting circuits; Fundamentals of electronics; High voltage distribution and equipment. Every practice question on this site is tagged to one of these domains.

The OR-JE exam has 52 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
