CD practice questions - frequently asked questions

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

The CD exam spans 117 domains: Abbreviations – Terms – Identification; Drafting Processes – Communication; Details – Notations; Site Drawings and Topography; Floor Plans and Layouts; Exterior Views – Elevations; Building Materials; Roofs and Roof Plans; Building Codes & ADA Codes; General Building Systems; Stairs and Steps; Electrical; HVAC; Schedules; Plumbing; Geometry – Lines – Math; Foundations. Every practice question on this site is tagged to one of these domains.

The CD exam has 400 questions and is completed in 2 hours 30 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
