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

The CETa exam spans 20 domains: Safety Precautions; Electrical Theory; Electronic Components; Electronic Circuits: Series and Parallel; Soldering - Desoldering Tools; Block Diagrams - Schematics - Wiring Diagrams; Cabling; Test Equipment and Measurements; Mathematics and Formulas; Power Supplies; Amplifiers; Interfacing of Electronics Products; Digital Concepts and Circuitry; Computer Electronics; Computer Applications and Software; Audio and Video Systems; Optical Electronics; Radio (RF) Communications Technology; Telecommunications Basics; Technician Work Procedures. Every practice question on this site is tagged to one of these domains.

The CETa exam has 100 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
