ACA practice questions - frequently asked questions

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

The ACA exam spans 3 domains: 3D component modeling and project files (61% of the exam); 3D assembly modeling and management (24% of the exam); Technical detailed drawing creation (15% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: 3D component modeling and project files 61%; 3D assembly modeling and management 24%; Technical detailed drawing creation 15%.

The ACA exam has 60 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
