CS practice questions - frequently asked questions

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

The CS exam spans 12 domains: Electrical Theory; Grounding; Basic Math Principles; Safety; Cable Properties; Cable Preparation; Splices; Terminations; Splicing and Terminating Materials; Diagrams and Drawings; Tools and Equipment; Management of Cable Splicing and Terminating Tasks. Every practice question on this site is tagged to one of these domains.
