AD practice questions - frequently asked questions

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

The AD exam spans 20 domains: Professional Drafting Practices in the Workplace – Communications; Drafting Equipment – Media – Reproduction; Architectural Sketching – Orthographic Projection; Lines – Lettering – General Terminology; Mathematics and Geometry; Architectural Products – Styles – History – Identification and Terminology; Site Layout – Identifications and Terminology; Drawing Identification – Architectural Numbering – Drawing Management; Dimensioning and Notations; Floor Plan Layout – Relationships – Identification and Terminology; HVAC – Plumbing – Electrical Plans – Identification and Terminology; Roof Plans – Identification and Terminology; Elevations; Framing – Framing Plans – Identification and Terminology; Foundation Plans – Identification and Terminology; Sections, Stairs and Steps; Building Codes and Governing Bodies; Schedules – Doors – Windows – Finishes; Estimations – Specifications – Calculations; Definitions and Building Materials. Every practice question on this site is tagged to one of these domains.

The AD 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.
